Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457974, here are decompositions:

5 + 31457969 = 31457974
71 + 31457903 = 31457974
113 + 31457861 = 31457974
131 + 31457843 = 31457974
257 + 31457717 = 31457974
293 + 31457681 = 31457974
347 + 31457627 = 31457974
461 + 31457513 = 31457974

Showing the first eight; more decompositions exist.
