Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537166, here are decompositions:

  • 13 + 31537153 = 31537166
  • 19 + 31537147 = 31537166
  • 79 + 31537087 = 31537166
  • 127 + 31537039 = 31537166
  • 139 + 31537027 = 31537166
  • 163 + 31537003 = 31537166
  • 223 + 31536943 = 31537166
  • 229 + 31536937 = 31537166

Showing the first eight; more decompositions exist.
