Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156942, here are decompositions:

  • 29 + 156913 = 156942
  • 41 + 156901 = 156942
  • 43 + 156899 = 156942
  • 101 + 156841 = 156942
  • 109 + 156833 = 156942
  • 193 + 156749 = 156942
  • 223 + 156719 = 156942
  • 239 + 156703 = 156942

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 156,942 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 156942 first appears in π at position 107,521 of the decimal expansion (the 107,521ordinal-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.
