Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559360, here are decompositions:

43 + 31559317 = 31559360
97 + 31559263 = 31559360
109 + 31559251 = 31559360
199 + 31559161 = 31559360
211 + 31559149 = 31559360
229 + 31559131 = 31559360
367 + 31558993 = 31559360
397 + 31558963 = 31559360

Showing the first eight; more decompositions exist.
