Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464036, here are decompositions:

5 + 31464031 = 31464036
73 + 31463963 = 31464036
127 + 31463909 = 31464036
139 + 31463897 = 31464036
157 + 31463879 = 31464036
179 + 31463857 = 31464036
193 + 31463843 = 31464036
229 + 31463807 = 31464036

Showing the first eight; more decompositions exist.
