Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609594, here are decompositions:

11 + 31609583 = 31609594
17 + 31609577 = 31609594
47 + 31609547 = 31609594
53 + 31609541 = 31609594
101 + 31609493 = 31609594
113 + 31609481 = 31609594
131 + 31609463 = 31609594
503 + 31609091 = 31609594

Showing the first eight; more decompositions exist.
