Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156250, here are decompositions:

  • 23 + 156227 = 156250
  • 131 + 156119 = 156250
  • 179 + 156071 = 156250
  • 191 + 156059 = 156250
  • 239 + 156011 = 156250
  • 359 + 155891 = 156250
  • 389 + 155861 = 156250
  • 401 + 155849 = 156250

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 156,250 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 156250 first appears in π at position 32,036 of the decimal expansion (the 32,036ordinal-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.
