Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559632, here are decompositions:

59 + 31559573 = 31559632
131 + 31559501 = 31559632
281 + 31559351 = 31559632
311 + 31559321 = 31559632
443 + 31559189 = 31559632
563 + 31559069 = 31559632
659 + 31558973 = 31559632
773 + 31558859 = 31559632

Showing the first eight; more decompositions exist.
