Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616888, here are decompositions:

31 + 31616857 = 31616888
139 + 31616749 = 31616888
181 + 31616707 = 31616888
211 + 31616677 = 31616888
241 + 31616647 = 31616888
349 + 31616539 = 31616888
367 + 31616521 = 31616888
379 + 31616509 = 31616888

Showing the first eight; more decompositions exist.
