Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610394, here are decompositions:

5 + 31610389 = 31610394
31 + 31610363 = 31610394
41 + 31610353 = 31610394
61 + 31610333 = 31610394
103 + 31610291 = 31610394
107 + 31610287 = 31610394
157 + 31610237 = 31610394
163 + 31610231 = 31610394

Showing the first eight; more decompositions exist.
