Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552016, here are decompositions:

19 + 31551997 = 31552016
37 + 31551979 = 31552016
79 + 31551937 = 31552016
157 + 31551859 = 31552016
163 + 31551853 = 31552016
283 + 31551733 = 31552016
439 + 31551577 = 31552016
499 + 31551517 = 31552016

Showing the first eight; more decompositions exist.
