Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625898, here are decompositions:

  • 79 + 31625819 = 31625898
  • 131 + 31625767 = 31625898
  • 137 + 31625761 = 31625898
  • 167 + 31625731 = 31625898
  • 251 + 31625647 = 31625898
  • 281 + 31625617 = 31625898
  • 331 + 31625567 = 31625898
  • 389 + 31625509 = 31625898

Showing the first eight; more decompositions exist.
