Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610250, here are decompositions:

13 + 31610237 = 31610250
19 + 31610231 = 31610250
37 + 31610213 = 31610250
53 + 31610197 = 31610250
79 + 31610171 = 31610250
107 + 31610143 = 31610250
109 + 31610141 = 31610250
137 + 31610113 = 31610250

Showing the first eight; more decompositions exist.
