Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628538, here are decompositions:

59 + 8628479 = 8628538
89 + 8628449 = 8628538
131 + 8628407 = 8628538
179 + 8628359 = 8628538
389 + 8628149 = 8628538
431 + 8628107 = 8628538
461 + 8628077 = 8628538
521 + 8628017 = 8628538

Showing the first eight; more decompositions exist.
