Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450064, here are decompositions:

3 + 31450061 = 31450064
7 + 31450057 = 31450064
31 + 31450033 = 31450064
43 + 31450021 = 31450064
73 + 31449991 = 31450064
97 + 31449967 = 31450064
127 + 31449937 = 31450064
193 + 31449871 = 31450064

Showing the first eight; more decompositions exist.
