Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738378, here are decompositions:

  • 79 + 8738299 = 8738378
  • 97 + 8738281 = 8738378
  • 139 + 8738239 = 8738378
  • 151 + 8738227 = 8738378
  • 277 + 8738101 = 8738378
  • 307 + 8738071 = 8738378
  • 331 + 8738047 = 8738378
  • 367 + 8738011 = 8738378

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,738,378 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8738378 first appears in π at position 614,335 of the decimal expansion (the 614,335ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
