Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559932, here are decompositions:

71 + 31559861 = 31559932
83 + 31559849 = 31559932
101 + 31559831 = 31559932
149 + 31559783 = 31559932
233 + 31559699 = 31559932
251 + 31559681 = 31559932
281 + 31559651 = 31559932
293 + 31559639 = 31559932

Showing the first eight; more decompositions exist.
