Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616330, here are decompositions:

3 + 31616327 = 31616330
43 + 31616287 = 31616330
73 + 31616257 = 31616330
79 + 31616251 = 31616330
157 + 31616173 = 31616330
181 + 31616149 = 31616330
271 + 31616059 = 31616330
283 + 31616047 = 31616330

Showing the first eight; more decompositions exist.
