Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66266, here are decompositions:

  • 97 + 66169 = 66266
  • 157 + 66109 = 66266
  • 163 + 66103 = 66266
  • 199 + 66067 = 66266
  • 229 + 66037 = 66266
  • 283 + 65983 = 66266
  • 337 + 65929 = 66266
  • 367 + 65899 = 66266

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66266 first appears in π at position 78,554 of the decimal expansion (the 78,554ordinal-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.
