Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538378, here are decompositions:

  • 11 + 538367 = 538378
  • 47 + 538331 = 538378
  • 131 + 538247 = 538378
  • 179 + 538199 = 538378
  • 227 + 538151 = 538378
  • 251 + 538127 = 538378
  • 257 + 538121 = 538378
  • 359 + 538019 = 538378

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 538,378 and was likely granted around 1894.

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

Position in π

The digit sequence 538378 first appears in π at position 201,414 of the decimal expansion (the 201,414ordinal-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.
