Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617360, here are decompositions:

  • 31 + 31617329 = 31617360
  • 67 + 31617293 = 31617360
  • 79 + 31617281 = 31617360
  • 107 + 31617253 = 31617360
  • 109 + 31617251 = 31617360
  • 179 + 31617181 = 31617360
  • 193 + 31617167 = 31617360
  • 211 + 31617149 = 31617360

Showing the first eight; more decompositions exist.
