Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610274, here are decompositions:

5 + 31610269 = 31610274
37 + 31610237 = 31610274
43 + 31610231 = 31610274
61 + 31610213 = 31610274
103 + 31610171 = 31610274
131 + 31610143 = 31610274
167 + 31610107 = 31610274
181 + 31610093 = 31610274

Showing the first eight; more decompositions exist.
