Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499442, here are decompositions:

  • 3 + 499439 = 499442
  • 19 + 499423 = 499442
  • 79 + 499363 = 499442
  • 283 + 499159 = 499442
  • 313 + 499129 = 499442
  • 379 + 499063 = 499442
  • 409 + 499033 = 499442
  • 421 + 499021 = 499442

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 499,442 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 499442 first appears in π at position 223,843 of the decimal expansion (the 223,843ordinal-suffix:rd 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.
