Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584424, here are decompositions:

  • 17 + 31584407 = 31584424
  • 23 + 31584401 = 31584424
  • 41 + 31584383 = 31584424
  • 101 + 31584323 = 31584424
  • 191 + 31584233 = 31584424
  • 227 + 31584197 = 31584424
  • 233 + 31584191 = 31584424
  • 251 + 31584173 = 31584424

Showing the first eight; more decompositions exist.
