Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66260, here are decompositions:

  • 151 + 66109 = 66260
  • 157 + 66103 = 66260
  • 193 + 66067 = 66260
  • 223 + 66037 = 66260
  • 277 + 65983 = 66260
  • 331 + 65929 = 66260
  • 379 + 65881 = 66260
  • 409 + 65851 = 66260

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66260 first appears in π at position 74,125 of the decimal expansion (the 74,125ordinal-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.
