Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457662, here are decompositions:

59 + 31457603 = 31457662
149 + 31457513 = 31457662
191 + 31457471 = 31457662
251 + 31457411 = 31457662
359 + 31457303 = 31457662
461 + 31457201 = 31457662
491 + 31457171 = 31457662
503 + 31457159 = 31457662

Showing the first eight; more decompositions exist.
