Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564048, here are decompositions:

59 + 31563989 = 31564048
101 + 31563947 = 31564048
107 + 31563941 = 31564048
137 + 31563911 = 31564048
149 + 31563899 = 31564048
167 + 31563881 = 31564048
311 + 31563737 = 31564048
401 + 31563647 = 31564048

Showing the first eight; more decompositions exist.
