Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532826, here are decompositions:

89 + 31532737 = 31532826
139 + 31532687 = 31532826
167 + 31532659 = 31532826
173 + 31532653 = 31532826
229 + 31532597 = 31532826
233 + 31532593 = 31532826
239 + 31532587 = 31532826
337 + 31532489 = 31532826

Showing the first eight; more decompositions exist.
