Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572496, here are decompositions:

  • 83 + 31572413 = 31572496
  • 107 + 31572389 = 31572496
  • 149 + 31572347 = 31572496
  • 173 + 31572323 = 31572496
  • 233 + 31572263 = 31572496
  • 269 + 31572227 = 31572496
  • 353 + 31572143 = 31572496
  • 467 + 31572029 = 31572496

Showing the first eight; more decompositions exist.
