Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527066, here are decompositions:

19 + 31527047 = 31527066
113 + 31526953 = 31527066
127 + 31526939 = 31527066
139 + 31526927 = 31527066
163 + 31526903 = 31527066
167 + 31526899 = 31527066
173 + 31526893 = 31527066
257 + 31526809 = 31527066

Showing the first eight; more decompositions exist.
