Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492400, here are decompositions:

  • 3 + 492397 = 492400
  • 11 + 492389 = 492400
  • 23 + 492377 = 492400
  • 101 + 492299 = 492400
  • 107 + 492293 = 492400
  • 149 + 492251 = 492400
  • 173 + 492227 = 492400
  • 317 + 492083 = 492400

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 492,400 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 492400 first appears in π at position 466,220 of the decimal expansion (the 466,220ordinal-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.
