Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494482, here are decompositions:

3 + 31494479 = 31494482
13 + 31494469 = 31494482
43 + 31494439 = 31494482
181 + 31494301 = 31494482
241 + 31494241 = 31494482
499 + 31493983 = 31494482
541 + 31493941 = 31494482
601 + 31493881 = 31494482

Showing the first eight; more decompositions exist.
