Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616204, here are decompositions:

31 + 31616173 = 31616204
157 + 31616047 = 31616204
163 + 31616041 = 31616204
181 + 31616023 = 31616204
211 + 31615993 = 31616204
283 + 31615921 = 31616204
313 + 31615891 = 31616204
397 + 31615807 = 31616204

Showing the first eight; more decompositions exist.
