Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616274, here are decompositions:

13 + 31616261 = 31616274
17 + 31616257 = 31616274
23 + 31616251 = 31616274
43 + 31616231 = 31616274
101 + 31616173 = 31616274
227 + 31616047 = 31616274
233 + 31616041 = 31616274
241 + 31616033 = 31616274

Showing the first eight; more decompositions exist.
