Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625032, here are decompositions:

  • 53 + 31624979 = 31625032
  • 233 + 31624799 = 31625032
  • 251 + 31624781 = 31625032
  • 269 + 31624763 = 31625032
  • 293 + 31624739 = 31625032
  • 359 + 31624673 = 31625032
  • 389 + 31624643 = 31625032
  • 401 + 31624631 = 31625032

Showing the first eight; more decompositions exist.
