Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493842, here are decompositions:

  • 29 + 493813 = 493842
  • 31 + 493811 = 493842
  • 109 + 493733 = 493842
  • 113 + 493729 = 493842
  • 131 + 493711 = 493842
  • 149 + 493693 = 493842
  • 199 + 493643 = 493842
  • 263 + 493579 = 493842

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 493,842 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 493842 first appears in π at position 498,708 of the decimal expansion (the 498,708ordinal-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.
