Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474976, here are decompositions:

  • 7 + 31474969 = 31474976
  • 103 + 31474873 = 31474976
  • 109 + 31474867 = 31474976
  • 193 + 31474783 = 31474976
  • 199 + 31474777 = 31474976
  • 229 + 31474747 = 31474976
  • 283 + 31474693 = 31474976
  • 307 + 31474669 = 31474976

Showing the first eight; more decompositions exist.
