Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546770, here are decompositions:

11 + 31546759 = 31546770
29 + 31546741 = 31546770
53 + 31546717 = 31546770
61 + 31546709 = 31546770
107 + 31546663 = 31546770
109 + 31546661 = 31546770
113 + 31546657 = 31546770
137 + 31546633 = 31546770

Showing the first eight; more decompositions exist.
