Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617524, here are decompositions:

31 + 31617493 = 31617524
67 + 31617457 = 31617524
151 + 31617373 = 31617524
163 + 31617361 = 31617524
241 + 31617283 = 31617524
271 + 31617253 = 31617524
607 + 31616917 = 31617524
751 + 31616773 = 31617524

Showing the first eight; more decompositions exist.
