Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539066, here are decompositions:

5 + 31539061 = 31539066
19 + 31539047 = 31539066
23 + 31539043 = 31539066
59 + 31539007 = 31539066
79 + 31538987 = 31539066
179 + 31538887 = 31539066
239 + 31538827 = 31539066
277 + 31538789 = 31539066

Showing the first eight; more decompositions exist.
