Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626860, here are decompositions:

13 + 8626847 = 8626860
19 + 8626841 = 8626860
29 + 8626831 = 8626860
37 + 8626823 = 8626860
41 + 8626819 = 8626860
59 + 8626801 = 8626860
83 + 8626777 = 8626860
97 + 8626763 = 8626860

Showing the first eight; more decompositions exist.
