Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22920, here are decompositions:

  • 13 + 22907 = 22920
  • 19 + 22901 = 22920
  • 43 + 22877 = 22920
  • 59 + 22861 = 22920
  • 61 + 22859 = 22920
  • 67 + 22853 = 22920
  • 103 + 22817 = 22920
  • 109 + 22811 = 22920

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22920 first appears in π at position 100,242 of the decimal expansion (the 100,242ordinal-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.
