Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66258, here are decompositions:

  • 19 + 66239 = 66258
  • 37 + 66221 = 66258
  • 67 + 66191 = 66258
  • 79 + 66179 = 66258
  • 89 + 66169 = 66258
  • 97 + 66161 = 66258
  • 149 + 66109 = 66258
  • 151 + 66107 = 66258

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66258 first appears in π at position 144,153 of the decimal expansion (the 144,153ordinal-suffix:rd 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.
