Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493578, here are decompositions:

  • 5 + 493573 = 493578
  • 11 + 493567 = 493578
  • 37 + 493541 = 493578
  • 47 + 493531 = 493578
  • 97 + 493481 = 493578
  • 131 + 493447 = 493578
  • 179 + 493399 = 493578
  • 181 + 493397 = 493578

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 493,578 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 493578 first appears in π at position 272,822 of the decimal expansion (the 272,822ordinal-suffix:nd 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.
