Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617244, here are decompositions:

5 + 31617239 = 31617244
167 + 31617077 = 31617244
233 + 31617011 = 31617244
257 + 31616987 = 31617244
293 + 31616951 = 31617244
311 + 31616933 = 31617244
353 + 31616891 = 31617244
557 + 31616687 = 31617244

Showing the first eight; more decompositions exist.
