Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626246, here are decompositions:

  • 13 + 31626233 = 31626246
  • 17 + 31626229 = 31626246
  • 37 + 31626209 = 31626246
  • 53 + 31626193 = 31626246
  • 79 + 31626167 = 31626246
  • 137 + 31626109 = 31626246
  • 167 + 31626079 = 31626246
  • 173 + 31626073 = 31626246

Showing the first eight; more decompositions exist.
