Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467756, here are decompositions:

29 + 31467727 = 31467756
37 + 31467719 = 31467756
79 + 31467677 = 31467756
109 + 31467647 = 31467756
163 + 31467593 = 31467756
167 + 31467589 = 31467756
197 + 31467559 = 31467756
223 + 31467533 = 31467756

Showing the first eight; more decompositions exist.
