Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584364, here are decompositions:

3 + 31584361 = 31584364
41 + 31584323 = 31584364
83 + 31584281 = 31584364
101 + 31584263 = 31584364
131 + 31584233 = 31584364
167 + 31584197 = 31584364
173 + 31584191 = 31584364
191 + 31584173 = 31584364

Showing the first eight; more decompositions exist.
