Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610368, here are decompositions:

5 + 31610363 = 31610368
29 + 31610339 = 31610368
89 + 31610279 = 31610368
131 + 31610237 = 31610368
137 + 31610231 = 31610368
197 + 31610171 = 31610368
227 + 31610141 = 31610368
359 + 31610009 = 31610368

Showing the first eight; more decompositions exist.
