Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154522, here are decompositions:

  • 29 + 154493 = 154522
  • 83 + 154439 = 154522
  • 113 + 154409 = 154522
  • 149 + 154373 = 154522
  • 293 + 154229 = 154522
  • 311 + 154211 = 154522
  • 443 + 154079 = 154522
  • 449 + 154073 = 154522

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 154,522 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 154522 first appears in π at position 694,096 of the decimal expansion (the 694,096ordinal-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.
