Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624586, here are decompositions:

  • 79 + 31624507 = 31624586
  • 109 + 31624477 = 31624586
  • 157 + 31624429 = 31624586
  • 163 + 31624423 = 31624586
  • 199 + 31624387 = 31624586
  • 223 + 31624363 = 31624586
  • 229 + 31624357 = 31624586
  • 439 + 31624147 = 31624586

Showing the first eight; more decompositions exist.
