Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607598, here are decompositions:

17 + 31607581 = 31607598
19 + 31607579 = 31607598
47 + 31607551 = 31607598
67 + 31607531 = 31607598
109 + 31607489 = 31607598
137 + 31607461 = 31607598
149 + 31607449 = 31607598
151 + 31607447 = 31607598

Showing the first eight; more decompositions exist.
