Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599624, here are decompositions:

13 + 31599611 = 31599624
61 + 31599563 = 31599624
71 + 31599553 = 31599624
73 + 31599551 = 31599624
137 + 31599487 = 31599624
193 + 31599431 = 31599624
271 + 31599353 = 31599624
283 + 31599341 = 31599624

Showing the first eight; more decompositions exist.
