Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6506, here are decompositions:

  • 37 + 6469 = 6506
  • 79 + 6427 = 6506
  • 109 + 6397 = 6506
  • 127 + 6379 = 6506
  • 139 + 6367 = 6506
  • 163 + 6343 = 6506
  • 229 + 6277 = 6506
  • 277 + 6229 = 6506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6506 first appears in π at position 11,828 of the decimal expansion (the 11,828ordinal-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.
