Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628586, here are decompositions:

107 + 8628479 = 8628586
137 + 8628449 = 8628586
179 + 8628407 = 8628586
227 + 8628359 = 8628586
233 + 8628353 = 8628586
293 + 8628293 = 8628586
353 + 8628233 = 8628586
383 + 8628203 = 8628586

Showing the first eight; more decompositions exist.
