Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457734, here are decompositions:

5 + 31457729 = 31457734
17 + 31457717 = 31457734
47 + 31457687 = 31457734
53 + 31457681 = 31457734
107 + 31457627 = 31457734
131 + 31457603 = 31457734
263 + 31457471 = 31457734
281 + 31457453 = 31457734

Showing the first eight; more decompositions exist.
