Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457762, here are decompositions:

3 + 31457759 = 31457762
19 + 31457743 = 31457762
43 + 31457719 = 31457762
151 + 31457611 = 31457762
283 + 31457479 = 31457762
313 + 31457449 = 31457762
379 + 31457383 = 31457762
421 + 31457341 = 31457762

Showing the first eight; more decompositions exist.
