Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616254, here are decompositions:

3 + 31616251 = 31616254
23 + 31616231 = 31616254
71 + 31616183 = 31616254
233 + 31616021 = 31616254
281 + 31615973 = 31616254
491 + 31615763 = 31616254
863 + 31615391 = 31616254
911 + 31615343 = 31616254

Showing the first eight; more decompositions exist.
