Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539084, here are decompositions:

11 + 31539073 = 31539084
23 + 31539061 = 31539084
37 + 31539047 = 31539084
41 + 31539043 = 31539084
97 + 31538987 = 31539084
197 + 31538887 = 31539084
257 + 31538827 = 31539084
277 + 31538807 = 31539084

Showing the first eight; more decompositions exist.
