Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23130, here are decompositions:

  • 13 + 23117 = 23130
  • 31 + 23099 = 23130
  • 43 + 23087 = 23130
  • 59 + 23071 = 23130
  • 67 + 23063 = 23130
  • 71 + 23059 = 23130
  • 73 + 23057 = 23130
  • 89 + 23041 = 23130

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23130 first appears in π at position 6,318 of the decimal expansion (the 6,318ordinal-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.
