Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596400, here are decompositions:

  • 83 + 31596317 = 31596400
  • 89 + 31596311 = 31596400
  • 107 + 31596293 = 31596400
  • 191 + 31596209 = 31596400
  • 257 + 31596143 = 31596400
  • 281 + 31596119 = 31596400
  • 359 + 31596041 = 31596400
  • 431 + 31595969 = 31596400

Showing the first eight; more decompositions exist.
