Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13210, here are decompositions:

  • 23 + 13187 = 13210
  • 47 + 13163 = 13210
  • 59 + 13151 = 13210
  • 83 + 13127 = 13210
  • 89 + 13121 = 13210
  • 101 + 13109 = 13210
  • 107 + 13103 = 13210
  • 167 + 13043 = 13210

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13210 first appears in π at position 28,730 of the decimal expansion (the 28,730ordinal-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.
