Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464930, here are decompositions:

47 + 31464883 = 31464930
103 + 31464827 = 31464930
109 + 31464821 = 31464930
149 + 31464781 = 31464930
173 + 31464757 = 31464930
199 + 31464731 = 31464930
229 + 31464701 = 31464930
281 + 31464649 = 31464930

Showing the first eight; more decompositions exist.
