Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493522, here are decompositions:

3 + 31493519 = 31493522
79 + 31493443 = 31493522
103 + 31493419 = 31493522
199 + 31493323 = 31493522
271 + 31493251 = 31493522
331 + 31493191 = 31493522
439 + 31493083 = 31493522
601 + 31492921 = 31493522

Showing the first eight; more decompositions exist.
