Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467690, here are decompositions:

13 + 31467677 = 31467690
43 + 31467647 = 31467690
97 + 31467593 = 31467690
101 + 31467589 = 31467690
103 + 31467587 = 31467690
131 + 31467559 = 31467690
139 + 31467551 = 31467690
151 + 31467539 = 31467690

Showing the first eight; more decompositions exist.
