Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616588, here are decompositions:

19 + 31616569 = 31616588
67 + 31616521 = 31616588
79 + 31616509 = 31616588
109 + 31616479 = 31616588
229 + 31616359 = 31616588
307 + 31616281 = 31616588
331 + 31616257 = 31616588
337 + 31616251 = 31616588

Showing the first eight; more decompositions exist.
