Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529980, here are decompositions:

3 + 31529977 = 31529980
11 + 31529969 = 31529980
47 + 31529933 = 31529980
89 + 31529891 = 31529980
137 + 31529843 = 31529980
197 + 31529783 = 31529980
263 + 31529717 = 31529980
311 + 31529669 = 31529980

Showing the first eight; more decompositions exist.
