Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530458, here are decompositions:

  • 7 + 31530451 = 31530458
  • 67 + 31530391 = 31530458
  • 109 + 31530349 = 31530458
  • 277 + 31530181 = 31530458
  • 397 + 31530061 = 31530458
  • 457 + 31530001 = 31530458
  • 577 + 31529881 = 31530458
  • 709 + 31529749 = 31530458

Showing the first eight; more decompositions exist.
