Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595524, here are decompositions:

  • 41 + 31595483 = 31595524
  • 131 + 31595393 = 31595524
  • 137 + 31595387 = 31595524
  • 251 + 31595273 = 31595524
  • 281 + 31595243 = 31595524
  • 347 + 31595177 = 31595524
  • 383 + 31595141 = 31595524
  • 461 + 31595063 = 31595524

Showing the first eight; more decompositions exist.
