Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616558, here are decompositions:

19 + 31616539 = 31616558
37 + 31616521 = 31616558
79 + 31616479 = 31616558
139 + 31616419 = 31616558
157 + 31616401 = 31616558
199 + 31616359 = 31616558
271 + 31616287 = 31616558
277 + 31616281 = 31616558

Showing the first eight; more decompositions exist.
