Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467138, here are decompositions:

5 + 31467133 = 31467138
11 + 31467127 = 31467138
67 + 31467071 = 31467138
71 + 31467067 = 31467138
127 + 31467011 = 31467138
139 + 31466999 = 31467138
149 + 31466989 = 31467138
239 + 31466899 = 31467138

Showing the first eight; more decompositions exist.
