Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449804, here are decompositions:

13 + 31449791 = 31449804
37 + 31449767 = 31449804
47 + 31449757 = 31449804
53 + 31449751 = 31449804
103 + 31449701 = 31449804
107 + 31449697 = 31449804
131 + 31449673 = 31449804
157 + 31449647 = 31449804

Showing the first eight; more decompositions exist.
