Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528610, here are decompositions:

31 + 31528579 = 31528610
37 + 31528573 = 31528610
79 + 31528531 = 31528610
109 + 31528501 = 31528610
151 + 31528459 = 31528610
163 + 31528447 = 31528610
283 + 31528327 = 31528610
331 + 31528279 = 31528610

Showing the first eight; more decompositions exist.
