Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467774, here are decompositions:

7 + 31467767 = 31467774
11 + 31467763 = 31467774
47 + 31467727 = 31467774
53 + 31467721 = 31467774
83 + 31467691 = 31467774
97 + 31467677 = 31467774
127 + 31467647 = 31467774
181 + 31467593 = 31467774

Showing the first eight; more decompositions exist.
