Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457316, here are decompositions:

5 + 31457311 = 31457316
13 + 31457303 = 31457316
19 + 31457297 = 31457316
29 + 31457287 = 31457316
47 + 31457269 = 31457316
89 + 31457227 = 31457316
113 + 31457203 = 31457316
157 + 31457159 = 31457316

Showing the first eight; more decompositions exist.
