Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539036, here are decompositions:

29 + 31539007 = 31539036
149 + 31538887 = 31539036
229 + 31538807 = 31539036
257 + 31538779 = 31539036
283 + 31538753 = 31539036
293 + 31538743 = 31539036
307 + 31538729 = 31539036
317 + 31538719 = 31539036

Showing the first eight; more decompositions exist.
