Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584276, here are decompositions:

13 + 31584263 = 31584276
29 + 31584247 = 31584276
43 + 31584233 = 31584276
79 + 31584197 = 31584276
83 + 31584193 = 31584276
103 + 31584173 = 31584276
137 + 31584139 = 31584276
233 + 31584043 = 31584276

Showing the first eight; more decompositions exist.
