Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628522, here are decompositions:

29 + 8628493 = 8628522
41 + 8628481 = 8628522
43 + 8628479 = 8628522
59 + 8628463 = 8628522
73 + 8628449 = 8628522
79 + 8628443 = 8628522
101 + 8628421 = 8628522
139 + 8628383 = 8628522

Showing the first eight; more decompositions exist.
