Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616618, here are decompositions:

79 + 31616539 = 31616618
97 + 31616521 = 31616618
109 + 31616509 = 31616618
139 + 31616479 = 31616618
199 + 31616419 = 31616618
331 + 31616287 = 31616618
337 + 31616281 = 31616618
367 + 31616251 = 31616618

Showing the first eight; more decompositions exist.
