Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464708, here are decompositions:

7 + 31464701 = 31464708
59 + 31464649 = 31464708
89 + 31464619 = 31464708
127 + 31464581 = 31464708
131 + 31464577 = 31464708
137 + 31464571 = 31464708
151 + 31464557 = 31464708
199 + 31464509 = 31464708

Showing the first eight; more decompositions exist.
