Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495018, here are decompositions:

  • 31 + 494987 = 495018
  • 59 + 494959 = 495018
  • 79 + 494939 = 495018
  • 101 + 494917 = 495018
  • 229 + 494789 = 495018
  • 257 + 494761 = 495018
  • 269 + 494749 = 495018
  • 281 + 494737 = 495018

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 495,018 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 495018 first appears in π at position 407,620 of the decimal expansion (the 407,620ordinal-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.
