Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464912, here are decompositions:

29 + 31464883 = 31464912
103 + 31464809 = 31464912
131 + 31464781 = 31464912
181 + 31464731 = 31464912
211 + 31464701 = 31464912
263 + 31464649 = 31464912
293 + 31464619 = 31464912
331 + 31464581 = 31464912

Showing the first eight; more decompositions exist.
