Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528682, here are decompositions:

13 + 31528669 = 31528682
61 + 31528621 = 31528682
103 + 31528579 = 31528682
109 + 31528573 = 31528682
151 + 31528531 = 31528682
181 + 31528501 = 31528682
223 + 31528459 = 31528682
571 + 31528111 = 31528682

Showing the first eight; more decompositions exist.
