Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457054, here are decompositions:

  • 3 + 31457051 = 31457054
  • 127 + 31456927 = 31457054
  • 151 + 31456903 = 31457054
  • 163 + 31456891 = 31457054
  • 313 + 31456741 = 31457054
  • 457 + 31456597 = 31457054
  • 523 + 31456531 = 31457054
  • 613 + 31456441 = 31457054

Showing the first eight; more decompositions exist.
