Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584370, here are decompositions:

47 + 31584323 = 31584370
71 + 31584299 = 31584370
89 + 31584281 = 31584370
107 + 31584263 = 31584370
137 + 31584233 = 31584370
173 + 31584197 = 31584370
179 + 31584191 = 31584370
197 + 31584173 = 31584370

Showing the first eight; more decompositions exist.
