Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1726, here are decompositions:

  • 3 + 1723 = 1726
  • 5 + 1721 = 1726
  • 17 + 1709 = 1726
  • 29 + 1697 = 1726
  • 59 + 1667 = 1726
  • 89 + 1637 = 1726
  • 107 + 1619 = 1726
  • 113 + 1613 = 1726

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1726 first appears in π at position 52,158 of the decimal expansion (the 52,158ordinal-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.
