Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616360, here are decompositions:

73 + 31616287 = 31616360
79 + 31616281 = 31616360
103 + 31616257 = 31616360
109 + 31616251 = 31616360
211 + 31616149 = 31616360
313 + 31616047 = 31616360
337 + 31616023 = 31616360
367 + 31615993 = 31616360

Showing the first eight; more decompositions exist.
