Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617364, here are decompositions:

3 + 31617361 = 31617364
71 + 31617293 = 31617364
83 + 31617281 = 31617364
113 + 31617251 = 31617364
197 + 31617167 = 31617364
263 + 31617101 = 31617364
353 + 31617011 = 31617364
431 + 31616933 = 31617364

Showing the first eight; more decompositions exist.
