Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616498, here are decompositions:

19 + 31616479 = 31616498
79 + 31616419 = 31616498
97 + 31616401 = 31616498
139 + 31616359 = 31616498
211 + 31616287 = 31616498
241 + 31616257 = 31616498
349 + 31616149 = 31616498
439 + 31616059 = 31616498

Showing the first eight; more decompositions exist.
