Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474982, here are decompositions:

  • 13 + 31474969 = 31474982
  • 109 + 31474873 = 31474982
  • 181 + 31474801 = 31474982
  • 199 + 31474783 = 31474982
  • 313 + 31474669 = 31474982
  • 433 + 31474549 = 31474982
  • 463 + 31474519 = 31474982
  • 619 + 31474363 = 31474982

Showing the first eight; more decompositions exist.
