Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585302, here are decompositions:

  • 13 + 31585289 = 31585302
  • 31 + 31585271 = 31585302
  • 41 + 31585261 = 31585302
  • 103 + 31585199 = 31585302
  • 109 + 31585193 = 31585302
  • 113 + 31585189 = 31585302
  • 131 + 31585171 = 31585302
  • 163 + 31585139 = 31585302

Showing the first eight; more decompositions exist.
