Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493184, here are decompositions:

13 + 31493171 = 31493184
31 + 31493153 = 31493184
53 + 31493131 = 31493184
101 + 31493083 = 31493184
127 + 31493057 = 31493184
131 + 31493053 = 31493184
137 + 31493047 = 31493184
167 + 31493017 = 31493184

Showing the first eight; more decompositions exist.
