Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610436, here are decompositions:

23 + 31610413 = 31610436
43 + 31610393 = 31610436
47 + 31610389 = 31610436
73 + 31610363 = 31610436
83 + 31610353 = 31610436
97 + 31610339 = 31610436
103 + 31610333 = 31610436
149 + 31610287 = 31610436

Showing the first eight; more decompositions exist.
