Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634738, here are decompositions:

41 + 8634697 = 8634738
59 + 8634679 = 8634738
61 + 8634677 = 8634738
67 + 8634671 = 8634738
71 + 8634667 = 8634738
109 + 8634629 = 8634738
157 + 8634581 = 8634738
181 + 8634557 = 8634738

Showing the first eight; more decompositions exist.
