Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632740, here are decompositions:

13 + 8632727 = 8632740
23 + 8632717 = 8632740
41 + 8632699 = 8632740
73 + 8632667 = 8632740
79 + 8632661 = 8632740
131 + 8632609 = 8632740
167 + 8632573 = 8632740
211 + 8632529 = 8632740

Showing the first eight; more decompositions exist.
