Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690862, here are decompositions:

41 + 8690821 = 8690862
73 + 8690789 = 8690862
79 + 8690783 = 8690862
149 + 8690713 = 8690862
179 + 8690683 = 8690862
199 + 8690663 = 8690862
223 + 8690639 = 8690862
251 + 8690611 = 8690862

Showing the first eight; more decompositions exist.
