Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539006, here are decompositions:

19 + 31538987 = 31539006
179 + 31538827 = 31539006
199 + 31538807 = 31539006
227 + 31538779 = 31539006
263 + 31538743 = 31539006
277 + 31538729 = 31539006
293 + 31538713 = 31539006
313 + 31538693 = 31539006

Showing the first eight; more decompositions exist.
