Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465654, here are decompositions:

  • 5 + 31465649 = 31465654
  • 23 + 31465631 = 31465654
  • 53 + 31465601 = 31465654
  • 83 + 31465571 = 31465654
  • 107 + 31465547 = 31465654
  • 173 + 31465481 = 31465654
  • 263 + 31465391 = 31465654
  • 431 + 31465223 = 31465654

Showing the first eight; more decompositions exist.
