Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463668, here are decompositions:

149 + 31463519 = 31463668
179 + 31463489 = 31463668
191 + 31463477 = 31463668
239 + 31463429 = 31463668
281 + 31463387 = 31463668
347 + 31463321 = 31463668
419 + 31463249 = 31463668
521 + 31463147 = 31463668

Showing the first eight; more decompositions exist.
