Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627578, here are decompositions:

5 + 8627573 = 8627578
17 + 8627561 = 8627578
131 + 8627447 = 8627578
137 + 8627441 = 8627578
149 + 8627429 = 8627578
227 + 8627351 = 8627578
257 + 8627321 = 8627578
431 + 8627147 = 8627578

Showing the first eight; more decompositions exist.
