Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545458, here are decompositions:

  • 29 + 545429 = 545458
  • 71 + 545387 = 545458
  • 167 + 545291 = 545458
  • 191 + 545267 = 545458
  • 227 + 545231 = 545458
  • 269 + 545189 = 545458
  • 317 + 545141 = 545458
  • 401 + 545057 = 545458

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 545,458 and was likely granted around 1895.

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

Position in π

The digit sequence 545458 first appears in π at position 804,890 of the decimal expansion (the 804,890ordinal-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.
