Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493282, here are decompositions:

31 + 31493251 = 31493282
151 + 31493131 = 31493282
199 + 31493083 = 31493282
229 + 31493053 = 31493282
349 + 31492933 = 31493282
433 + 31492849 = 31493282
619 + 31492663 = 31493282
631 + 31492651 = 31493282

Showing the first eight; more decompositions exist.
