Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464866, here are decompositions:

79 + 31464787 = 31464866
109 + 31464757 = 31464866
157 + 31464709 = 31464866
373 + 31464493 = 31464866
439 + 31464427 = 31464866
457 + 31464409 = 31464866
673 + 31464193 = 31464866
787 + 31464079 = 31464866

Showing the first eight; more decompositions exist.
