Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559270, here are decompositions:

7 + 31559263 = 31559270
19 + 31559251 = 31559270
31 + 31559239 = 31559270
109 + 31559161 = 31559270
139 + 31559131 = 31559270
199 + 31559071 = 31559270
277 + 31558993 = 31559270
307 + 31558963 = 31559270

Showing the first eight; more decompositions exist.
