Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457592, here are decompositions:

79 + 31457513 = 31457592
113 + 31457479 = 31457592
139 + 31457453 = 31457592
181 + 31457411 = 31457592
251 + 31457341 = 31457592
263 + 31457329 = 31457592
281 + 31457311 = 31457592
389 + 31457203 = 31457592

Showing the first eight; more decompositions exist.
