Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627584, here are decompositions:

3 + 8627581 = 8627584
11 + 8627573 = 8627584
23 + 8627561 = 8627584
71 + 8627513 = 8627584
137 + 8627447 = 8627584
167 + 8627417 = 8627584
227 + 8627357 = 8627584
233 + 8627351 = 8627584

Showing the first eight; more decompositions exist.
