Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536798, here are decompositions:

5 + 31536793 = 31536798
67 + 31536731 = 31536798
79 + 31536719 = 31536798
101 + 31536697 = 31536798
191 + 31536607 = 31536798
269 + 31536529 = 31536798
277 + 31536521 = 31536798
317 + 31536481 = 31536798

Showing the first eight; more decompositions exist.
