Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463622, here are decompositions:

31 + 31463591 = 31463622
89 + 31463533 = 31463622
103 + 31463519 = 31463622
139 + 31463483 = 31463622
163 + 31463459 = 31463622
193 + 31463429 = 31463622
233 + 31463389 = 31463622
269 + 31463353 = 31463622

Showing the first eight; more decompositions exist.
