Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9880, here are decompositions:

  • 23 + 9857 = 9880
  • 29 + 9851 = 9880
  • 41 + 9839 = 9880
  • 47 + 9833 = 9880
  • 89 + 9791 = 9880
  • 113 + 9767 = 9880
  • 131 + 9749 = 9880
  • 137 + 9743 = 9880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9880 first appears in π at position 12,447 of the decimal expansion (the 12,447ordinal-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.
