Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616598, here are decompositions:

19 + 31616579 = 31616598
29 + 31616569 = 31616598
37 + 31616561 = 31616598
59 + 31616539 = 31616598
89 + 31616509 = 31616598
179 + 31616419 = 31616598
197 + 31616401 = 31616598
229 + 31616369 = 31616598

Showing the first eight; more decompositions exist.
