Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588492, here are decompositions:

  • 29 + 31588463 = 31588492
  • 53 + 31588439 = 31588492
  • 179 + 31588313 = 31588492
  • 239 + 31588253 = 31588492
  • 293 + 31588199 = 31588492
  • 389 + 31588103 = 31588492
  • 431 + 31588061 = 31588492
  • 569 + 31587923 = 31588492

Showing the first eight; more decompositions exist.
