Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526330, here are decompositions:

  • 13 + 31526317 = 31526330
  • 103 + 31526227 = 31526330
  • 109 + 31526221 = 31526330
  • 139 + 31526191 = 31526330
  • 349 + 31525981 = 31526330
  • 373 + 31525957 = 31526330
  • 379 + 31525951 = 31526330
  • 421 + 31525909 = 31526330

Showing the first eight; more decompositions exist.
