Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486066, here are decompositions:

107 + 31485959 = 31486066
113 + 31485953 = 31486066
149 + 31485917 = 31486066
173 + 31485893 = 31486066
233 + 31485833 = 31486066
263 + 31485803 = 31486066
317 + 31485749 = 31486066
467 + 31485599 = 31486066

Showing the first eight; more decompositions exist.
