Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143678, here are decompositions:

  • 61 + 143617 = 143678
  • 109 + 143569 = 143678
  • 127 + 143551 = 143678
  • 151 + 143527 = 143678
  • 211 + 143467 = 143678
  • 277 + 143401 = 143678
  • 349 + 143329 = 143678
  • 397 + 143281 = 143678

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 143,678 and was likely granted around 1873.

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

Position in π

The digit sequence 143678 first appears in π at position 626,211 of the decimal expansion (the 626,211ordinal-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.
