Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610272, here are decompositions:

3 + 31610269 = 31610272
41 + 31610231 = 31610272
59 + 31610213 = 31610272
101 + 31610171 = 31610272
131 + 31610141 = 31610272
179 + 31610093 = 31610272
191 + 31610081 = 31610272
233 + 31610039 = 31610272

Showing the first eight; more decompositions exist.
