Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457764, here are decompositions:

5 + 31457759 = 31457764
11 + 31457753 = 31457764
47 + 31457717 = 31457764
83 + 31457681 = 31457764
137 + 31457627 = 31457764
251 + 31457513 = 31457764
293 + 31457471 = 31457764
311 + 31457453 = 31457764

Showing the first eight; more decompositions exist.
