Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457632, here are decompositions:

5 + 31457627 = 31457632
29 + 31457603 = 31457632
179 + 31457453 = 31457632
431 + 31457201 = 31457632
461 + 31457171 = 31457632
593 + 31457039 = 31457632
683 + 31456949 = 31457632
863 + 31456769 = 31457632

Showing the first eight; more decompositions exist.
