Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474656, here are decompositions:

  • 79 + 31474577 = 31474656
  • 97 + 31474559 = 31474656
  • 107 + 31474549 = 31474656
  • 137 + 31474519 = 31474656
  • 167 + 31474489 = 31474656
  • 223 + 31474433 = 31474656
  • 233 + 31474423 = 31474656
  • 293 + 31474363 = 31474656

Showing the first eight; more decompositions exist.
