Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607926, here are decompositions:

5 + 31607921 = 31607926
17 + 31607909 = 31607926
23 + 31607903 = 31607926
29 + 31607897 = 31607926
59 + 31607867 = 31607926
137 + 31607789 = 31607926
179 + 31607747 = 31607926
239 + 31607687 = 31607926

Showing the first eight; more decompositions exist.
