Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628508, here are decompositions:

29 + 8628479 = 8628508
59 + 8628449 = 8628508
101 + 8628407 = 8628508
131 + 8628377 = 8628508
149 + 8628359 = 8628508
347 + 8628161 = 8628508
359 + 8628149 = 8628508
401 + 8628107 = 8628508

Showing the first eight; more decompositions exist.
