Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589492, here are decompositions:

  • 19 + 31589473 = 31589492
  • 31 + 31589461 = 31589492
  • 139 + 31589353 = 31589492
  • 163 + 31589329 = 31589492
  • 199 + 31589293 = 31589492
  • 241 + 31589251 = 31589492
  • 373 + 31589119 = 31589492
  • 499 + 31588993 = 31589492

Showing the first eight; more decompositions exist.
