Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546906, here are decompositions:

  • 59 + 31546847 = 31546906
  • 89 + 31546817 = 31546906
  • 107 + 31546799 = 31546906
  • 197 + 31546709 = 31546906
  • 269 + 31546637 = 31546906
  • 353 + 31546553 = 31546906
  • 449 + 31546457 = 31546906
  • 557 + 31546349 = 31546906

Showing the first eight; more decompositions exist.
