Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599450, here are decompositions:

11 + 31599439 = 31599450
19 + 31599431 = 31599450
61 + 31599389 = 31599450
97 + 31599353 = 31599450
101 + 31599349 = 31599450
109 + 31599341 = 31599450
137 + 31599313 = 31599450
191 + 31599259 = 31599450

Showing the first eight; more decompositions exist.
