Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620826, here are decompositions:

79 + 8620747 = 8620826
103 + 8620723 = 8620826
139 + 8620687 = 8620826
163 + 8620663 = 8620826
223 + 8620603 = 8620826
283 + 8620543 = 8620826
397 + 8620429 = 8620826
433 + 8620393 = 8620826

Showing the first eight; more decompositions exist.
