Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457348, here are decompositions:

7 + 31457341 = 31457348
19 + 31457329 = 31457348
37 + 31457311 = 31457348
61 + 31457287 = 31457348
79 + 31457269 = 31457348
199 + 31457149 = 31457348
229 + 31457119 = 31457348
277 + 31457071 = 31457348

Showing the first eight; more decompositions exist.
