Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467804, here are decompositions:

37 + 31467767 = 31467804
41 + 31467763 = 31467804
83 + 31467721 = 31467804
113 + 31467691 = 31467804
127 + 31467677 = 31467804
157 + 31467647 = 31467804
211 + 31467593 = 31467804
233 + 31467571 = 31467804

Showing the first eight; more decompositions exist.
