Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464188, here are decompositions:

109 + 31464079 = 31464188
127 + 31464061 = 31464188
157 + 31464031 = 31464188
229 + 31463959 = 31464188
277 + 31463911 = 31464188
331 + 31463857 = 31464188
409 + 31463779 = 31464188
421 + 31463767 = 31464188

Showing the first eight; more decompositions exist.
