Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495158, here are decompositions:

  • 7 + 495151 = 495158
  • 19 + 495139 = 495158
  • 199 + 494959 = 495158
  • 241 + 494917 = 495158
  • 397 + 494761 = 495158
  • 409 + 494749 = 495158
  • 421 + 494737 = 495158
  • 439 + 494719 = 495158

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 495,158 and was likely granted around 1893.

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

Position in π

The digit sequence 495158 first appears in π at position 433,362 of the decimal expansion (the 433,362ordinal-suffix:nd 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.
