Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454502, here are decompositions:

  • 5 + 31454497 = 31454502
  • 19 + 31454483 = 31454502
  • 41 + 31454461 = 31454502
  • 61 + 31454441 = 31454502
  • 71 + 31454431 = 31454502
  • 113 + 31454389 = 31454502
  • 151 + 31454351 = 31454502
  • 181 + 31454321 = 31454502

Showing the first eight; more decompositions exist.
