Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616562, here are decompositions:

23 + 31616539 = 31616562
41 + 31616521 = 31616562
53 + 31616509 = 31616562
83 + 31616479 = 31616562
139 + 31616423 = 31616562
151 + 31616411 = 31616562
181 + 31616381 = 31616562
193 + 31616369 = 31616562

Showing the first eight; more decompositions exist.
