Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532914, here are decompositions:

41 + 31532873 = 31532914
47 + 31532867 = 31532914
137 + 31532777 = 31532914
227 + 31532687 = 31532914
317 + 31532597 = 31532914
653 + 31532261 = 31532914
773 + 31532141 = 31532914
797 + 31532117 = 31532914

Showing the first eight; more decompositions exist.
