Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542066, here are decompositions:

29 + 31542037 = 31542066
43 + 31542023 = 31542066
53 + 31542013 = 31542066
89 + 31541977 = 31542066
163 + 31541903 = 31542066
167 + 31541899 = 31542066
173 + 31541893 = 31542066
197 + 31541869 = 31542066

Showing the first eight; more decompositions exist.
