Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464846, here are decompositions:

19 + 31464827 = 31464846
37 + 31464809 = 31464846
59 + 31464787 = 31464846
89 + 31464757 = 31464846
137 + 31464709 = 31464846
197 + 31464649 = 31464846
227 + 31464619 = 31464846
229 + 31464617 = 31464846

Showing the first eight; more decompositions exist.
