Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467660, here are decompositions:

13 + 31467647 = 31467660
67 + 31467593 = 31467660
71 + 31467589 = 31467660
73 + 31467587 = 31467660
89 + 31467571 = 31467660
101 + 31467559 = 31467660
109 + 31467551 = 31467660
127 + 31467533 = 31467660

Showing the first eight; more decompositions exist.
