Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625228, here are decompositions:

  • 79 + 31625149 = 31625228
  • 97 + 31625131 = 31625228
  • 277 + 31624951 = 31625228
  • 307 + 31624921 = 31625228
  • 367 + 31624861 = 31625228
  • 379 + 31624849 = 31625228
  • 421 + 31624807 = 31625228
  • 487 + 31624741 = 31625228

Showing the first eight; more decompositions exist.
