Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457364, here are decompositions:

17 + 31457347 = 31457364
23 + 31457341 = 31457364
53 + 31457311 = 31457364
61 + 31457303 = 31457364
67 + 31457297 = 31457364
97 + 31457267 = 31457364
137 + 31457227 = 31457364
163 + 31457201 = 31457364

Showing the first eight; more decompositions exist.
