Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464966, here are decompositions:

19 + 31464947 = 31464966
83 + 31464883 = 31464966
139 + 31464827 = 31464966
157 + 31464809 = 31464966
179 + 31464787 = 31464966
257 + 31464709 = 31464966
317 + 31464649 = 31464966
347 + 31464619 = 31464966

Showing the first eight; more decompositions exist.
