Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528390, here are decompositions:

  • 17 + 31528373 = 31528390
  • 41 + 31528349 = 31528390
  • 53 + 31528337 = 31528390
  • 107 + 31528283 = 31528390
  • 149 + 31528241 = 31528390
  • 233 + 31528157 = 31528390
  • 239 + 31528151 = 31528390
  • 263 + 31528127 = 31528390

Showing the first eight; more decompositions exist.
