Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467156, here are decompositions:

23 + 31467133 = 31467156
29 + 31467127 = 31467156
53 + 31467103 = 31467156
67 + 31467089 = 31467156
73 + 31467083 = 31467156
89 + 31467067 = 31467156
157 + 31466999 = 31467156
163 + 31466993 = 31467156

Showing the first eight; more decompositions exist.
