Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616480, here are decompositions:

61 + 31616419 = 31616480
79 + 31616401 = 31616480
193 + 31616287 = 31616480
199 + 31616281 = 31616480
223 + 31616257 = 31616480
229 + 31616251 = 31616480
307 + 31616173 = 31616480
331 + 31616149 = 31616480

Showing the first eight; more decompositions exist.
