Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489450, here are decompositions:

  • 11 + 489439 = 489450
  • 19 + 489431 = 489450
  • 23 + 489427 = 489450
  • 41 + 489409 = 489450
  • 43 + 489407 = 489450
  • 61 + 489389 = 489450
  • 83 + 489367 = 489450
  • 89 + 489361 = 489450

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 489,450 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 489450 first appears in π at position 806,574 of the decimal expansion (the 806,574ordinal-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.
