Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464798, here are decompositions:

11 + 31464787 = 31464798
17 + 31464781 = 31464798
41 + 31464757 = 31464798
67 + 31464731 = 31464798
89 + 31464709 = 31464798
97 + 31464701 = 31464798
149 + 31464649 = 31464798
179 + 31464619 = 31464798

Showing the first eight; more decompositions exist.
