Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523822, here are decompositions:

19 + 31523803 = 31523822
61 + 31523761 = 31523822
73 + 31523749 = 31523822
163 + 31523659 = 31523822
223 + 31523599 = 31523822
283 + 31523539 = 31523822
349 + 31523473 = 31523822
571 + 31523251 = 31523822

Showing the first eight; more decompositions exist.
