Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464774, here are decompositions:

17 + 31464757 = 31464774
43 + 31464731 = 31464774
73 + 31464701 = 31464774
157 + 31464617 = 31464774
193 + 31464581 = 31464774
197 + 31464577 = 31464774
227 + 31464547 = 31464774
281 + 31464493 = 31464774

Showing the first eight; more decompositions exist.
