Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151882, here are decompositions:

  • 11 + 151871 = 151882
  • 41 + 151841 = 151882
  • 83 + 151799 = 151882
  • 113 + 151769 = 151882
  • 149 + 151733 = 151882
  • 179 + 151703 = 151882
  • 239 + 151643 = 151882
  • 251 + 151631 = 151882

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 151,882 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 151882 first appears in π at position 50,488 of the decimal expansion (the 50,488ordinal-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.
