Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455276, here are decompositions:

5 + 31455271 = 31455276
7 + 31455269 = 31455276
37 + 31455239 = 31455276
53 + 31455223 = 31455276
67 + 31455209 = 31455276
79 + 31455197 = 31455276
137 + 31455139 = 31455276
157 + 31455119 = 31455276

Showing the first eight; more decompositions exist.
