Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641626, here are decompositions:

5 + 8641621 = 8641626
13 + 8641613 = 8641626
23 + 8641603 = 8641626
79 + 8641547 = 8641626
83 + 8641543 = 8641626
107 + 8641519 = 8641626
109 + 8641517 = 8641626
113 + 8641513 = 8641626

Showing the first eight; more decompositions exist.
