Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465256, here are decompositions:

13 + 31465243 = 31465256
73 + 31465183 = 31465256
79 + 31465177 = 31465256
103 + 31465153 = 31465256
127 + 31465129 = 31465256
157 + 31465099 = 31465256
223 + 31465033 = 31465256
283 + 31464973 = 31465256

Showing the first eight; more decompositions exist.
