Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467724, here are decompositions:

3 + 31467721 = 31467724
5 + 31467719 = 31467724
47 + 31467677 = 31467724
131 + 31467593 = 31467724
137 + 31467587 = 31467724
173 + 31467551 = 31467724
191 + 31467533 = 31467724
227 + 31467497 = 31467724

Showing the first eight; more decompositions exist.
