Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493124, here are decompositions:

41 + 31493083 = 31493124
67 + 31493057 = 31493124
71 + 31493053 = 31493124
107 + 31493017 = 31493124
127 + 31492997 = 31493124
181 + 31492943 = 31493124
191 + 31492933 = 31493124
277 + 31492847 = 31493124

Showing the first eight; more decompositions exist.
