Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16742, here are decompositions:

  • 13 + 16729 = 16742
  • 43 + 16699 = 16742
  • 109 + 16633 = 16742
  • 139 + 16603 = 16742
  • 181 + 16561 = 16742
  • 223 + 16519 = 16742
  • 331 + 16411 = 16742
  • 373 + 16369 = 16742

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16742 first appears in π at position 59,918 of the decimal expansion (the 59,918ordinal-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.
