Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573086, here are decompositions:

29 + 31573057 = 31573086
59 + 31573027 = 31573086
79 + 31573007 = 31573086
107 + 31572979 = 31573086
137 + 31572949 = 31573086
263 + 31572823 = 31573086
277 + 31572809 = 31573086
317 + 31572769 = 31573086

Showing the first eight; more decompositions exist.
