Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158756, here are decompositions:

  • 7 + 158749 = 158756
  • 109 + 158647 = 158756
  • 139 + 158617 = 158756
  • 193 + 158563 = 158756
  • 229 + 158527 = 158756
  • 307 + 158449 = 158756
  • 313 + 158443 = 158756
  • 337 + 158419 = 158756

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 158,756 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 158756 first appears in π at position 43,701 of the decimal expansion (the 43,701ordinal-suffix:st 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.
