Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616698, here are decompositions:

5 + 31616693 = 31616698
11 + 31616687 = 31616698
137 + 31616561 = 31616698
317 + 31616381 = 31616698
359 + 31616339 = 31616698
401 + 31616297 = 31616698
467 + 31616231 = 31616698
479 + 31616219 = 31616698

Showing the first eight; more decompositions exist.
