Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610636, here are decompositions:

7 + 31610629 = 31610636
67 + 31610569 = 31610636
73 + 31610563 = 31610636
97 + 31610539 = 31610636
199 + 31610437 = 31610636
223 + 31610413 = 31610636
283 + 31610353 = 31610636
349 + 31610287 = 31610636

Showing the first eight; more decompositions exist.
