Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479966, here are decompositions:

  • 5 + 31479961 = 31479966
  • 17 + 31479949 = 31479966
  • 19 + 31479947 = 31479966
  • 109 + 31479857 = 31479966
  • 137 + 31479829 = 31479966
  • 149 + 31479817 = 31479966
  • 163 + 31479803 = 31479966
  • 173 + 31479793 = 31479966

Showing the first eight; more decompositions exist.
