Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472550, here are decompositions:

  • 13 + 31472537 = 31472550
  • 61 + 31472489 = 31472550
  • 71 + 31472479 = 31472550
  • 101 + 31472449 = 31472550
  • 113 + 31472437 = 31472550
  • 191 + 31472359 = 31472550
  • 199 + 31472351 = 31472550
  • 211 + 31472339 = 31472550

Showing the first eight; more decompositions exist.
