Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463638, here are decompositions:

47 + 31463591 = 31463638
131 + 31463507 = 31463638
149 + 31463489 = 31463638
179 + 31463459 = 31463638
251 + 31463387 = 31463638
317 + 31463321 = 31463638
389 + 31463249 = 31463638
491 + 31463147 = 31463638

Showing the first eight; more decompositions exist.
