Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559536, here are decompositions:

89 + 31559447 = 31559536
317 + 31559219 = 31559536
347 + 31559189 = 31559536
443 + 31559093 = 31559536
467 + 31559069 = 31559536
509 + 31559027 = 31559536
563 + 31558973 = 31559536
653 + 31558883 = 31559536

Showing the first eight; more decompositions exist.
