Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559776, here are decompositions:

5 + 31559771 = 31559776
89 + 31559687 = 31559776
137 + 31559639 = 31559776
239 + 31559537 = 31559776
359 + 31559417 = 31559776
557 + 31559219 = 31559776
569 + 31559207 = 31559776
587 + 31559189 = 31559776

Showing the first eight; more decompositions exist.
