Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486006, here are decompositions:

47 + 31485959 = 31486006
53 + 31485953 = 31486006
89 + 31485917 = 31486006
113 + 31485893 = 31486006
173 + 31485833 = 31486006
239 + 31485767 = 31486006
257 + 31485749 = 31486006
263 + 31485743 = 31486006

Showing the first eight; more decompositions exist.
