Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67818, here are decompositions:

  • 11 + 67807 = 67818
  • 17 + 67801 = 67818
  • 29 + 67789 = 67818
  • 41 + 67777 = 67818
  • 59 + 67759 = 67818
  • 61 + 67757 = 67818
  • 67 + 67751 = 67818
  • 109 + 67709 = 67818

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 67818 first appears in π at position 84,796 of the decimal expansion (the 84,796ordinal-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.
