Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474826, here are decompositions:

  • 43 + 31474783 = 31474826
  • 79 + 31474747 = 31474826
  • 139 + 31474687 = 31474826
  • 157 + 31474669 = 31474826
  • 277 + 31474549 = 31474826
  • 307 + 31474519 = 31474826
  • 337 + 31474489 = 31474826
  • 463 + 31474363 = 31474826

Showing the first eight; more decompositions exist.
