Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464158, here are decompositions:

79 + 31464079 = 31464158
97 + 31464061 = 31464158
127 + 31464031 = 31464158
157 + 31464001 = 31464158
199 + 31463959 = 31464158
331 + 31463827 = 31464158
379 + 31463779 = 31464158
571 + 31463587 = 31464158

Showing the first eight; more decompositions exist.
