Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522066, here are decompositions:

5 + 31522061 = 31522066
47 + 31522019 = 31522066
53 + 31522013 = 31522066
89 + 31521977 = 31522066
113 + 31521953 = 31522066
179 + 31521887 = 31522066
353 + 31521713 = 31522066
383 + 31521683 = 31522066

Showing the first eight; more decompositions exist.
