Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586424, here are decompositions:

  • 17 + 31586407 = 31586424
  • 47 + 31586377 = 31586424
  • 73 + 31586351 = 31586424
  • 113 + 31586311 = 31586424
  • 137 + 31586287 = 31586424
  • 151 + 31586273 = 31586424
  • 167 + 31586257 = 31586424
  • 277 + 31586147 = 31586424

Showing the first eight; more decompositions exist.
