Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690826, here are decompositions:

5 + 8690821 = 8690826
13 + 8690813 = 8690826
29 + 8690797 = 8690826
37 + 8690789 = 8690826
43 + 8690783 = 8690826
59 + 8690767 = 8690826
113 + 8690713 = 8690826
149 + 8690677 = 8690826

Showing the first eight; more decompositions exist.
