Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499142, here are decompositions:

  • 3 + 499139 = 499142
  • 13 + 499129 = 499142
  • 43 + 499099 = 499142
  • 79 + 499063 = 499142
  • 103 + 499039 = 499142
  • 109 + 499033 = 499142
  • 181 + 498961 = 499142
  • 211 + 498931 = 499142

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 499,142 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 499142 first appears in π at position 427,623 of the decimal expansion (the 427,623ordinal-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.
