Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449696, here are decompositions:

7 + 31449689 = 31449696
17 + 31449679 = 31449696
23 + 31449673 = 31449696
59 + 31449637 = 31449696
67 + 31449629 = 31449696
107 + 31449589 = 31449696
127 + 31449569 = 31449696
139 + 31449557 = 31449696

Showing the first eight; more decompositions exist.
