Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559330, here are decompositions:

13 + 31559317 = 31559330
67 + 31559263 = 31559330
79 + 31559251 = 31559330
181 + 31559149 = 31559330
199 + 31559131 = 31559330
337 + 31558993 = 31559330
367 + 31558963 = 31559330
373 + 31558957 = 31559330

Showing the first eight; more decompositions exist.
