Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450074, here are decompositions:

13 + 31450061 = 31450074
17 + 31450057 = 31450074
31 + 31450043 = 31450074
41 + 31450033 = 31450074
43 + 31450031 = 31450074
53 + 31450021 = 31450074
83 + 31449991 = 31450074
107 + 31449967 = 31450074

Showing the first eight; more decompositions exist.
