Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514470, here are decompositions:

  • 41 + 31514429 = 31514470
  • 47 + 31514423 = 31514470
  • 173 + 31514297 = 31514470
  • 179 + 31514291 = 31514470
  • 311 + 31514159 = 31514470
  • 389 + 31514081 = 31514470
  • 503 + 31513967 = 31514470
  • 593 + 31513877 = 31514470

Showing the first eight; more decompositions exist.
