Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526082, here are decompositions:

13 + 31526069 = 31526082
19 + 31526063 = 31526082
31 + 31526051 = 31526082
61 + 31526021 = 31526082
101 + 31525981 = 31526082
131 + 31525951 = 31526082
163 + 31525919 = 31526082
173 + 31525909 = 31526082

Showing the first eight; more decompositions exist.
