Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464090, here are decompositions:

11 + 31464079 = 31464090
23 + 31464067 = 31464090
29 + 31464061 = 31464090
43 + 31464047 = 31464090
59 + 31464031 = 31464090
89 + 31464001 = 31464090
127 + 31463963 = 31464090
131 + 31463959 = 31464090

Showing the first eight; more decompositions exist.
