Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610376, here are decompositions:

13 + 31610363 = 31610376
23 + 31610353 = 31610376
37 + 31610339 = 31610376
43 + 31610333 = 31610376
59 + 31610317 = 31610376
89 + 31610287 = 31610376
97 + 31610279 = 31610376
107 + 31610269 = 31610376

Showing the first eight; more decompositions exist.
