Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539046, here are decompositions:

3 + 31539043 = 31539046
59 + 31538987 = 31539046
239 + 31538807 = 31539046
257 + 31538789 = 31539046
293 + 31538753 = 31539046
317 + 31538729 = 31539046
353 + 31538693 = 31539046
467 + 31538579 = 31539046

Showing the first eight; more decompositions exist.
