Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463588, here are decompositions:

  • 61 + 31463527 = 31463588
  • 181 + 31463407 = 31463588
  • 199 + 31463389 = 31463588
  • 271 + 31463317 = 31463588
  • 307 + 31463281 = 31463588
  • 421 + 31463167 = 31463588
  • 619 + 31462969 = 31463588
  • 691 + 31462897 = 31463588

Showing the first eight; more decompositions exist.
