Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690856, here are decompositions:

29 + 8690827 = 8690856
43 + 8690813 = 8690856
59 + 8690797 = 8690856
67 + 8690789 = 8690856
73 + 8690783 = 8690856
89 + 8690767 = 8690856
173 + 8690683 = 8690856
179 + 8690677 = 8690856

Showing the first eight; more decompositions exist.
