Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559848, here are decompositions:

17 + 31559831 = 31559848
71 + 31559777 = 31559848
149 + 31559699 = 31559848
167 + 31559681 = 31559848
197 + 31559651 = 31559848
311 + 31559537 = 31559848
347 + 31559501 = 31559848
401 + 31559447 = 31559848

Showing the first eight; more decompositions exist.
