Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610586, here are decompositions:

5 + 31610581 = 31610586
13 + 31610573 = 31610586
17 + 31610569 = 31610586
23 + 31610563 = 31610586
47 + 31610539 = 31610586
67 + 31610519 = 31610586
83 + 31610503 = 31610586
149 + 31610437 = 31610586

Showing the first eight; more decompositions exist.
