Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16782, here are decompositions:

  • 19 + 16763 = 16782
  • 23 + 16759 = 16782
  • 41 + 16741 = 16782
  • 53 + 16729 = 16782
  • 79 + 16703 = 16782
  • 83 + 16699 = 16782
  • 89 + 16693 = 16782
  • 109 + 16673 = 16782

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16782 first appears in π at position 75,592 of the decimal expansion (the 75,592ordinal-suffix:nd 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.
