Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464804, here are decompositions:

17 + 31464787 = 31464804
23 + 31464781 = 31464804
47 + 31464757 = 31464804
73 + 31464731 = 31464804
103 + 31464701 = 31464804
223 + 31464581 = 31464804
227 + 31464577 = 31464804
233 + 31464571 = 31464804

Showing the first eight; more decompositions exist.
