Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616354, here are decompositions:

67 + 31616287 = 31616354
73 + 31616281 = 31616354
97 + 31616257 = 31616354
103 + 31616251 = 31616354
181 + 31616173 = 31616354
241 + 31616113 = 31616354
307 + 31616047 = 31616354
313 + 31616041 = 31616354

Showing the first eight; more decompositions exist.
