Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133886, here are decompositions:

  • 13 + 133873 = 133886
  • 43 + 133843 = 133886
  • 73 + 133813 = 133886
  • 163 + 133723 = 133886
  • 229 + 133657 = 133886
  • 367 + 133519 = 133886
  • 439 + 133447 = 133886
  • 499 + 133387 = 133886

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 133,886 and was likely granted around 1872.

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

Position in π

The digit sequence 133886 first appears in π at position 495,666 of the decimal expansion (the 495,666ordinal-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.
