Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536888, here are decompositions:

17 + 31536871 = 31536888
41 + 31536847 = 31536888
59 + 31536829 = 31536888
67 + 31536821 = 31536888
157 + 31536731 = 31536888
181 + 31536707 = 31536888
191 + 31536697 = 31536888
281 + 31536607 = 31536888

Showing the first eight; more decompositions exist.
