Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475456, here are decompositions:

  • 3 + 31475453 = 31475456
  • 13 + 31475443 = 31475456
  • 139 + 31475317 = 31475456
  • 349 + 31475107 = 31475456
  • 367 + 31475089 = 31475456
  • 373 + 31475083 = 31475456
  • 457 + 31474999 = 31475456
  • 487 + 31474969 = 31475456

Showing the first eight; more decompositions exist.
