Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467700, here are decompositions:

23 + 31467677 = 31467700
53 + 31467647 = 31467700
107 + 31467593 = 31467700
113 + 31467587 = 31467700
149 + 31467551 = 31467700
167 + 31467533 = 31467700
191 + 31467509 = 31467700
197 + 31467503 = 31467700

Showing the first eight; more decompositions exist.
