Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610396, here are decompositions:

3 + 31610393 = 31610396
7 + 31610389 = 31610396
43 + 31610353 = 31610396
79 + 31610317 = 31610396
109 + 31610287 = 31610396
127 + 31610269 = 31610396
199 + 31610197 = 31610396
283 + 31610113 = 31610396

Showing the first eight; more decompositions exist.
