Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492890, here are decompositions:

  • 7 + 492883 = 492890
  • 19 + 492871 = 492890
  • 37 + 492853 = 492890
  • 109 + 492781 = 492890
  • 127 + 492763 = 492890
  • 271 + 492619 = 492890
  • 367 + 492523 = 492890
  • 379 + 492511 = 492890

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 492,890 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 492890 first appears in π at position 423,978 of the decimal expansion (the 423,978ordinal-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.
