Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10172, here are decompositions:

  • 3 + 10169 = 10172
  • 13 + 10159 = 10172
  • 31 + 10141 = 10172
  • 61 + 10111 = 10172
  • 73 + 10099 = 10172
  • 79 + 10093 = 10172
  • 103 + 10069 = 10172
  • 163 + 10009 = 10172

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10172 first appears in π at position 8,040 of the decimal expansion (the 8,040ordinal-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.
