Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65506, here are decompositions:

  • 59 + 65447 = 65506
  • 83 + 65423 = 65506
  • 113 + 65393 = 65506
  • 149 + 65357 = 65506
  • 179 + 65327 = 65506
  • 197 + 65309 = 65506
  • 239 + 65267 = 65506
  • 293 + 65213 = 65506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65506 first appears in π at position 164,700 of the decimal expansion (the 164,700ordinal-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.
