Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610232, here are decompositions:

19 + 31610213 = 31610232
61 + 31610171 = 31610232
89 + 31610143 = 31610232
139 + 31610093 = 31610232
149 + 31610083 = 31610232
151 + 31610081 = 31610232
193 + 31610039 = 31610232
223 + 31610009 = 31610232

Showing the first eight; more decompositions exist.
