Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626182, here are decompositions:

  • 73 + 31626109 = 31626182
  • 103 + 31626079 = 31626182
  • 109 + 31626073 = 31626182
  • 163 + 31626019 = 31626182
  • 229 + 31625953 = 31626182
  • 271 + 31625911 = 31626182
  • 409 + 31625773 = 31626182
  • 421 + 31625761 = 31626182

Showing the first eight; more decompositions exist.
