Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156628, here are decompositions:

  • 5 + 156623 = 156628
  • 89 + 156539 = 156628
  • 107 + 156521 = 156628
  • 137 + 156491 = 156628
  • 191 + 156437 = 156628
  • 257 + 156371 = 156628
  • 281 + 156347 = 156628
  • 359 + 156269 = 156628

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 156,628 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 156628 first appears in π at position 316,579 of the decimal expansion (the 316,579ordinal-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.
