Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599680, here are decompositions:

31 + 31599649 = 31599680
127 + 31599553 = 31599680
181 + 31599499 = 31599680
193 + 31599487 = 31599680
241 + 31599439 = 31599680
331 + 31599349 = 31599680
367 + 31599313 = 31599680
373 + 31599307 = 31599680

Showing the first eight; more decompositions exist.
