Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528922, here are decompositions:

13 + 31528909 = 31528922
79 + 31528843 = 31528922
109 + 31528813 = 31528922
181 + 31528741 = 31528922
193 + 31528729 = 31528922
199 + 31528723 = 31528922
349 + 31528573 = 31528922
421 + 31528501 = 31528922

Showing the first eight; more decompositions exist.
