Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610460, here are decompositions:

23 + 31610437 = 31610460
47 + 31610413 = 31610460
67 + 31610393 = 31610460
71 + 31610389 = 31610460
97 + 31610363 = 31610460
107 + 31610353 = 31610460
127 + 31610333 = 31610460
173 + 31610287 = 31610460

Showing the first eight; more decompositions exist.
