Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599630, here are decompositions:

19 + 31599611 = 31599630
31 + 31599599 = 31599630
67 + 31599563 = 31599630
79 + 31599551 = 31599630
131 + 31599499 = 31599630
191 + 31599439 = 31599630
199 + 31599431 = 31599630
241 + 31599389 = 31599630

Showing the first eight; more decompositions exist.
