Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522584, here are decompositions:

  • 31 + 31522553 = 31522584
  • 43 + 31522541 = 31522584
  • 61 + 31522523 = 31522584
  • 151 + 31522433 = 31522584
  • 173 + 31522411 = 31522584
  • 211 + 31522373 = 31522584
  • 227 + 31522357 = 31522584
  • 257 + 31522327 = 31522584

Showing the first eight; more decompositions exist.
