Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576068, here are decompositions:

19 + 31576049 = 31576068
31 + 31576037 = 31576068
37 + 31576031 = 31576068
59 + 31576009 = 31576068
61 + 31576007 = 31576068
67 + 31576001 = 31576068
131 + 31575937 = 31576068
151 + 31575917 = 31576068

Showing the first eight; more decompositions exist.
