Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506224, here are decompositions:

  • 31 + 31506193 = 31506224
  • 163 + 31506061 = 31506224
  • 193 + 31506031 = 31506224
  • 241 + 31505983 = 31506224
  • 457 + 31505767 = 31506224
  • 487 + 31505737 = 31506224
  • 523 + 31505701 = 31506224
  • 601 + 31505623 = 31506224

Showing the first eight; more decompositions exist.
