Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464162, here are decompositions:

13 + 31464149 = 31464162
19 + 31464143 = 31464162
83 + 31464079 = 31464162
101 + 31464061 = 31464162
131 + 31464031 = 31464162
199 + 31463963 = 31464162
241 + 31463921 = 31464162
251 + 31463911 = 31464162

Showing the first eight; more decompositions exist.
