Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463608, here are decompositions:

17 + 31463591 = 31463608
89 + 31463519 = 31463608
101 + 31463507 = 31463608
131 + 31463477 = 31463608
149 + 31463459 = 31463608
179 + 31463429 = 31463608
347 + 31463261 = 31463608
359 + 31463249 = 31463608

Showing the first eight; more decompositions exist.
