Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616200, here are decompositions:

17 + 31616183 = 31616200
71 + 31616129 = 31616200
131 + 31616069 = 31616200
167 + 31616033 = 31616200
179 + 31616021 = 31616200
191 + 31616009 = 31616200
227 + 31615973 = 31616200
281 + 31615919 = 31616200

Showing the first eight; more decompositions exist.
