Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8900, here are decompositions:

  • 7 + 8893 = 8900
  • 13 + 8887 = 8900
  • 37 + 8863 = 8900
  • 61 + 8839 = 8900
  • 79 + 8821 = 8900
  • 97 + 8803 = 8900
  • 139 + 8761 = 8900
  • 163 + 8737 = 8900

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8900 first appears in π at position 2,600 of the decimal expansion (the 2,600ordinal-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.
