Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596070, here are decompositions:

  • 3 + 31596067 = 31596070
  • 29 + 31596041 = 31596070
  • 41 + 31596029 = 31596070
  • 101 + 31595969 = 31596070
  • 197 + 31595873 = 31596070
  • 239 + 31595831 = 31596070
  • 263 + 31595807 = 31596070
  • 293 + 31595777 = 31596070

Showing the first eight; more decompositions exist.
