Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457562, here are decompositions:

5 + 31457557 = 31457562
83 + 31457479 = 31457562
109 + 31457453 = 31457562
113 + 31457449 = 31457562
151 + 31457411 = 31457562
179 + 31457383 = 31457562
233 + 31457329 = 31457562
251 + 31457311 = 31457562

Showing the first eight; more decompositions exist.
