Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628492, here are decompositions:

11 + 8628481 = 8628492
13 + 8628479 = 8628492
29 + 8628463 = 8628492
43 + 8628449 = 8628492
71 + 8628421 = 8628492
109 + 8628383 = 8628492
139 + 8628353 = 8628492
199 + 8628293 = 8628492

Showing the first eight; more decompositions exist.
