Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634690, here are decompositions:

11 + 8634679 = 8634690
13 + 8634677 = 8634690
19 + 8634671 = 8634690
23 + 8634667 = 8634690
61 + 8634629 = 8634690
73 + 8634617 = 8634690
109 + 8634581 = 8634690
139 + 8634551 = 8634690

Showing the first eight; more decompositions exist.
