Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545624, here are decompositions:

  • 13 + 31545611 = 31545624
  • 17 + 31545607 = 31545624
  • 137 + 31545487 = 31545624
  • 223 + 31545401 = 31545624
  • 233 + 31545391 = 31545624
  • 251 + 31545373 = 31545624
  • 281 + 31545343 = 31545624
  • 293 + 31545331 = 31545624

Showing the first eight; more decompositions exist.
