Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610166, here are decompositions:

23 + 31610143 = 31610166
53 + 31610113 = 31610166
59 + 31610107 = 31610166
73 + 31610093 = 31610166
83 + 31610083 = 31610166
103 + 31610063 = 31610166
127 + 31610039 = 31610166
157 + 31610009 = 31610166

Showing the first eight; more decompositions exist.
