Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609606, here are decompositions:

23 + 31609583 = 31609606
29 + 31609577 = 31609606
59 + 31609547 = 31609606
107 + 31609499 = 31609606
113 + 31609493 = 31609606
137 + 31609469 = 31609606
317 + 31609289 = 31609606
383 + 31609223 = 31609606

Showing the first eight; more decompositions exist.
