Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493222, here are decompositions:

31 + 31493191 = 31493222
139 + 31493083 = 31493222
193 + 31493029 = 31493222
373 + 31492849 = 31493222
421 + 31492801 = 31493222
571 + 31492651 = 31493222
619 + 31492603 = 31493222
751 + 31492471 = 31493222

Showing the first eight; more decompositions exist.
