Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542244, here are decompositions:

  • 11 + 31542233 = 31542244
  • 47 + 31542197 = 31542244
  • 131 + 31542113 = 31542244
  • 233 + 31542011 = 31542244
  • 263 + 31541981 = 31542244
  • 311 + 31541933 = 31542244
  • 353 + 31541891 = 31542244
  • 593 + 31541651 = 31542244

Showing the first eight; more decompositions exist.
