Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457682, here are decompositions:

41 + 31457641 = 31457682
71 + 31457611 = 31457682
79 + 31457603 = 31457682
211 + 31457471 = 31457682
229 + 31457453 = 31457682
233 + 31457449 = 31457682
271 + 31457411 = 31457682
353 + 31457329 = 31457682

Showing the first eight; more decompositions exist.
