Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599776, here are decompositions:

3 + 31599773 = 31599776
73 + 31599703 = 31599776
127 + 31599649 = 31599776
223 + 31599553 = 31599776
277 + 31599499 = 31599776
337 + 31599439 = 31599776
463 + 31599313 = 31599776
619 + 31599157 = 31599776

Showing the first eight; more decompositions exist.
