Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156884, here are decompositions:

  • 43 + 156841 = 156884
  • 61 + 156823 = 156884
  • 67 + 156817 = 156884
  • 103 + 156781 = 156884
  • 151 + 156733 = 156884
  • 157 + 156727 = 156884
  • 181 + 156703 = 156884
  • 193 + 156691 = 156884

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 156,884 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 156884 first appears in π at position 191,306 of the decimal expansion (the 191,306ordinal-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.
