Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464938, here are decompositions:

151 + 31464787 = 31464938
157 + 31464781 = 31464938
181 + 31464757 = 31464938
229 + 31464709 = 31464938
367 + 31464571 = 31464938
457 + 31464481 = 31464938
487 + 31464451 = 31464938
499 + 31464439 = 31464938

Showing the first eight; more decompositions exist.
