Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589230, here are decompositions:

  • 47 + 31589183 = 31589230
  • 131 + 31589099 = 31589230
  • 173 + 31589057 = 31589230
  • 251 + 31588979 = 31589230
  • 383 + 31588847 = 31589230
  • 521 + 31588709 = 31589230
  • 557 + 31588673 = 31589230
  • 587 + 31588643 = 31589230

Showing the first eight; more decompositions exist.
