Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610600, here are decompositions:

13 + 31610587 = 31610600
19 + 31610581 = 31610600
31 + 31610569 = 31610600
37 + 31610563 = 31610600
61 + 31610539 = 31610600
79 + 31610521 = 31610600
97 + 31610503 = 31610600
163 + 31610437 = 31610600

Showing the first eight; more decompositions exist.
