Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543822, here are decompositions:

5 + 31543817 = 31543822
53 + 31543769 = 31543822
59 + 31543763 = 31543822
71 + 31543751 = 31543822
131 + 31543691 = 31543822
179 + 31543643 = 31543822
251 + 31543571 = 31543822
293 + 31543529 = 31543822

Showing the first eight; more decompositions exist.
