Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610732, here are decompositions:

3 + 31610729 = 31610732
103 + 31610629 = 31610732
151 + 31610581 = 31610732
163 + 31610569 = 31610732
193 + 31610539 = 31610732
211 + 31610521 = 31610732
229 + 31610503 = 31610732
379 + 31610353 = 31610732

Showing the first eight; more decompositions exist.
