Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464666, here are decompositions:

17 + 31464649 = 31464666
47 + 31464619 = 31464666
89 + 31464577 = 31464666
109 + 31464557 = 31464666
157 + 31464509 = 31464666
173 + 31464493 = 31464666
223 + 31464443 = 31464666
227 + 31464439 = 31464666

Showing the first eight; more decompositions exist.
