Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133778, here are decompositions:

  • 61 + 133717 = 133778
  • 67 + 133711 = 133778
  • 109 + 133669 = 133778
  • 181 + 133597 = 133778
  • 331 + 133447 = 133778
  • 457 + 133321 = 133778
  • 499 + 133279 = 133778
  • 577 + 133201 = 133778

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 133,778 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 133778 first appears in π at position 90,406 of the decimal expansion (the 90,406ordinal-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.
