Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493538, here are decompositions:

  • 7 + 493531 = 493538
  • 139 + 493399 = 493538
  • 307 + 493231 = 493538
  • 337 + 493201 = 493538
  • 379 + 493159 = 493538
  • 571 + 492967 = 493538
  • 739 + 492799 = 493538
  • 757 + 492781 = 493538

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 493,538 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 493538 first appears in π at position 994,909 of the decimal expansion (the 994,909ordinal-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.
