Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506446, here are decompositions:

  • 3 + 31506443 = 31506446
  • 73 + 31506373 = 31506446
  • 79 + 31506367 = 31506446
  • 163 + 31506283 = 31506446
  • 199 + 31506247 = 31506446
  • 457 + 31505989 = 31506446
  • 463 + 31505983 = 31506446
  • 487 + 31505959 = 31506446

Showing the first eight; more decompositions exist.
