Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517032, here are decompositions:

5 + 31517027 = 31517032
11 + 31517021 = 31517032
59 + 31516973 = 31517032
191 + 31516841 = 31517032
251 + 31516781 = 31517032
401 + 31516631 = 31517032
419 + 31516613 = 31517032
461 + 31516571 = 31517032

Showing the first eight; more decompositions exist.
