Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547610, here are decompositions:

19 + 31547591 = 31547610
53 + 31547557 = 31547610
71 + 31547539 = 31547610
79 + 31547531 = 31547610
103 + 31547507 = 31547610
131 + 31547479 = 31547610
139 + 31547471 = 31547610
151 + 31547459 = 31547610

Showing the first eight; more decompositions exist.
