Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616300, here are decompositions:

3 + 31616297 = 31616300
13 + 31616287 = 31616300
19 + 31616281 = 31616300
43 + 31616257 = 31616300
127 + 31616173 = 31616300
151 + 31616149 = 31616300
241 + 31616059 = 31616300
277 + 31616023 = 31616300

Showing the first eight; more decompositions exist.
