Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457084, here are decompositions:

  • 3 + 31457081 = 31457084
  • 13 + 31457071 = 31457084
  • 157 + 31456927 = 31457084
  • 181 + 31456903 = 31457084
  • 193 + 31456891 = 31457084
  • 433 + 31456651 = 31457084
  • 487 + 31456597 = 31457084
  • 643 + 31456441 = 31457084

Showing the first eight; more decompositions exist.
