Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9860, here are decompositions:

  • 3 + 9857 = 9860
  • 31 + 9829 = 9860
  • 43 + 9817 = 9860
  • 73 + 9787 = 9860
  • 79 + 9781 = 9860
  • 127 + 9733 = 9860
  • 139 + 9721 = 9860
  • 163 + 9697 = 9860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9860 first appears in π at position 549 of the decimal expansion (the 549ordinal-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.
