Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626856, here are decompositions:

37 + 8626819 = 8626856
79 + 8626777 = 8626856
109 + 8626747 = 8626856
157 + 8626699 = 8626856
307 + 8626549 = 8626856
349 + 8626507 = 8626856
397 + 8626459 = 8626856
439 + 8626417 = 8626856

Showing the first eight; more decompositions exist.
