Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71968, here are decompositions:

  • 5 + 71963 = 71968
  • 59 + 71909 = 71968
  • 89 + 71879 = 71968
  • 101 + 71867 = 71968
  • 107 + 71861 = 71968
  • 131 + 71837 = 71968
  • 179 + 71789 = 71968
  • 191 + 71777 = 71968

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71968 first appears in π at position 82,214 of the decimal expansion (the 82,214ordinal-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.
