Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450068, here are decompositions:

7 + 31450061 = 31450068
11 + 31450057 = 31450068
37 + 31450031 = 31450068
47 + 31450021 = 31450068
79 + 31449989 = 31450068
101 + 31449967 = 31450068
131 + 31449937 = 31450068
137 + 31449931 = 31450068

Showing the first eight; more decompositions exist.
