Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188156, here are decompositions:

  • 13 + 188143 = 188156
  • 19 + 188137 = 188156
  • 127 + 188029 = 188156
  • 139 + 188017 = 188156
  • 193 + 187963 = 188156
  • 229 + 187927 = 188156
  • 313 + 187843 = 188156
  • 457 + 187699 = 188156

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 188,156 and was likely granted around 1875.

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

Position in π

The digit sequence 188156 first appears in π at position 813,479 of the decimal expansion (the 813,479ordinal-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.
