Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626264, here are decompositions:

  • 17 + 31626247 = 31626264
  • 31 + 31626233 = 31626264
  • 67 + 31626197 = 31626264
  • 71 + 31626193 = 31626264
  • 73 + 31626191 = 31626264
  • 97 + 31626167 = 31626264
  • 191 + 31626073 = 31626264
  • 211 + 31626053 = 31626264

Showing the first eight; more decompositions exist.
