Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625940, here are decompositions:

  • 23 + 31625917 = 31625940
  • 29 + 31625911 = 31625940
  • 97 + 31625843 = 31625940
  • 163 + 31625777 = 31625940
  • 167 + 31625773 = 31625940
  • 173 + 31625767 = 31625940
  • 179 + 31625761 = 31625940
  • 293 + 31625647 = 31625940

Showing the first eight; more decompositions exist.
