Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79878, here are decompositions:

  • 5 + 79873 = 79878
  • 11 + 79867 = 79878
  • 17 + 79861 = 79878
  • 31 + 79847 = 79878
  • 37 + 79841 = 79878
  • 61 + 79817 = 79878
  • 67 + 79811 = 79878
  • 101 + 79777 = 79878

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 79878 first appears in π at position 60,260 of the decimal expansion (the 60,260ordinal-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.
