Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533266, here are decompositions:

  • 7 + 31533259 = 31533266
  • 139 + 31533127 = 31533266
  • 307 + 31532959 = 31533266
  • 367 + 31532899 = 31533266
  • 433 + 31532833 = 31533266
  • 607 + 31532659 = 31533266
  • 613 + 31532653 = 31533266
  • 673 + 31532593 = 31533266

Showing the first eight; more decompositions exist.
