Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610256, here are decompositions:

19 + 31610237 = 31610256
43 + 31610213 = 31610256
59 + 31610197 = 31610256
113 + 31610143 = 31610256
149 + 31610107 = 31610256
163 + 31610093 = 31610256
173 + 31610083 = 31610256
193 + 31610063 = 31610256

Showing the first eight; more decompositions exist.
