Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478034, here are decompositions:

11 + 31478023 = 31478034
17 + 31478017 = 31478034
41 + 31477993 = 31478034
43 + 31477991 = 31478034
67 + 31477967 = 31478034
83 + 31477951 = 31478034
97 + 31477937 = 31478034
127 + 31477907 = 31478034

Showing the first eight; more decompositions exist.
