Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610442, here are decompositions:

5 + 31610437 = 31610442
29 + 31610413 = 31610442
53 + 31610389 = 31610442
79 + 31610363 = 31610442
89 + 31610353 = 31610442
103 + 31610339 = 31610442
109 + 31610333 = 31610442
151 + 31610291 = 31610442

Showing the first eight; more decompositions exist.
