Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610196, here are decompositions:

53 + 31610143 = 31610196
83 + 31610113 = 31610196
89 + 31610107 = 31610196
103 + 31610093 = 31610196
113 + 31610083 = 31610196
157 + 31610039 = 31610196
173 + 31610023 = 31610196
223 + 31609973 = 31610196

Showing the first eight; more decompositions exist.
