Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465086, here are decompositions:

17 + 31465069 = 31465086
47 + 31465039 = 31465086
53 + 31465033 = 31465086
83 + 31465003 = 31465086
113 + 31464973 = 31465086
139 + 31464947 = 31465086
277 + 31464809 = 31465086
467 + 31464619 = 31465086

Showing the first eight; more decompositions exist.
