Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584306, here are decompositions:

7 + 31584299 = 31584306
43 + 31584263 = 31584306
59 + 31584247 = 31584306
73 + 31584233 = 31584306
109 + 31584197 = 31584306
113 + 31584193 = 31584306
163 + 31584143 = 31584306
167 + 31584139 = 31584306

Showing the first eight; more decompositions exist.
