Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559608, here are decompositions:

71 + 31559537 = 31559608
107 + 31559501 = 31559608
137 + 31559471 = 31559608
191 + 31559417 = 31559608
257 + 31559351 = 31559608
389 + 31559219 = 31559608
401 + 31559207 = 31559608
419 + 31559189 = 31559608

Showing the first eight; more decompositions exist.
