Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43880, here are decompositions:

  • 13 + 43867 = 43880
  • 79 + 43801 = 43880
  • 97 + 43783 = 43880
  • 103 + 43777 = 43880
  • 127 + 43753 = 43880
  • 163 + 43717 = 43880
  • 211 + 43669 = 43880
  • 229 + 43651 = 43880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43880 first appears in π at position 13,665 of the decimal expansion (the 13,665ordinal-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.
