Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559298, here are decompositions:

47 + 31559251 = 31559298
59 + 31559239 = 31559298
79 + 31559219 = 31559298
109 + 31559189 = 31559298
137 + 31559161 = 31559298
149 + 31559149 = 31559298
167 + 31559131 = 31559298
227 + 31559071 = 31559298

Showing the first eight; more decompositions exist.
