Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462372, here are decompositions:

  • 23 + 31462349 = 31462372
  • 59 + 31462313 = 31462372
  • 83 + 31462289 = 31462372
  • 239 + 31462133 = 31462372
  • 269 + 31462103 = 31462372
  • 449 + 31461923 = 31462372
  • 479 + 31461893 = 31462372
  • 521 + 31461851 = 31462372

Showing the first eight; more decompositions exist.
