Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708730, here are decompositions:

13 + 8708717 = 8708730
29 + 8708701 = 8708730
67 + 8708663 = 8708730
73 + 8708657 = 8708730
103 + 8708627 = 8708730
109 + 8708621 = 8708730
113 + 8708617 = 8708730
139 + 8708591 = 8708730

Showing the first eight; more decompositions exist.
