Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133928, here are decompositions:

  • 97 + 133831 = 133928
  • 127 + 133801 = 133928
  • 211 + 133717 = 133928
  • 271 + 133657 = 133928
  • 331 + 133597 = 133928
  • 409 + 133519 = 133928
  • 541 + 133387 = 133928
  • 577 + 133351 = 133928

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 133,928 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 133928 first appears in π at position 40,519 of the decimal expansion (the 40,519ordinal-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.
