Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454844, here are decompositions:

  • 7 + 31454837 = 31454844
  • 17 + 31454827 = 31454844
  • 61 + 31454783 = 31454844
  • 103 + 31454741 = 31454844
  • 107 + 31454737 = 31454844
  • 163 + 31454681 = 31454844
  • 191 + 31454653 = 31454844
  • 193 + 31454651 = 31454844

Showing the first eight; more decompositions exist.
