Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500996, here are decompositions:

17 + 31500979 = 31500996
19 + 31500977 = 31500996
29 + 31500967 = 31500996
73 + 31500923 = 31500996
97 + 31500899 = 31500996
179 + 31500817 = 31500996
199 + 31500797 = 31500996
223 + 31500773 = 31500996

Showing the first eight; more decompositions exist.
