Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22900, here are decompositions:

  • 23 + 22877 = 22900
  • 29 + 22871 = 22900
  • 41 + 22859 = 22900
  • 47 + 22853 = 22900
  • 83 + 22817 = 22900
  • 89 + 22811 = 22900
  • 113 + 22787 = 22900
  • 131 + 22769 = 22900

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22900 first appears in π at position 49,984 of the decimal expansion (the 49,984ordinal-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.
