Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87876, here are decompositions:

  • 7 + 87869 = 87876
  • 23 + 87853 = 87876
  • 43 + 87833 = 87876
  • 73 + 87803 = 87876
  • 79 + 87797 = 87876
  • 83 + 87793 = 87876
  • 109 + 87767 = 87876
  • 137 + 87739 = 87876

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 87876 first appears in π at position 59,553 of the decimal expansion (the 59,553ordinal-suffix:rd 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.
