Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493094, here are decompositions:

11 + 31493083 = 31493094
37 + 31493057 = 31493094
41 + 31493053 = 31493094
47 + 31493047 = 31493094
97 + 31492997 = 31493094
103 + 31492991 = 31493094
131 + 31492963 = 31493094
151 + 31492943 = 31493094

Showing the first eight; more decompositions exist.
