Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550424, here are decompositions:

  • 23 + 31550401 = 31550424
  • 53 + 31550371 = 31550424
  • 67 + 31550357 = 31550424
  • 71 + 31550353 = 31550424
  • 97 + 31550327 = 31550424
  • 137 + 31550287 = 31550424
  • 167 + 31550257 = 31550424
  • 173 + 31550251 = 31550424

Showing the first eight; more decompositions exist.
