Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79880, here are decompositions:

  • 7 + 79873 = 79880
  • 13 + 79867 = 79880
  • 19 + 79861 = 79880
  • 37 + 79843 = 79880
  • 67 + 79813 = 79880
  • 79 + 79801 = 79880
  • 103 + 79777 = 79880
  • 181 + 79699 = 79880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 79880 first appears in π at position 52,469 of the decimal expansion (the 52,469ordinal-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.
