Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560298, here are decompositions:

5 + 31560293 = 31560298
47 + 31560251 = 31560298
59 + 31560239 = 31560298
71 + 31560227 = 31560298
191 + 31560107 = 31560298
239 + 31560059 = 31560298
251 + 31560047 = 31560298
269 + 31560029 = 31560298

Showing the first eight; more decompositions exist.
