Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690788, here are decompositions:

5 + 8690783 = 8690788
47 + 8690741 = 8690788
149 + 8690639 = 8690788
257 + 8690531 = 8690788
311 + 8690477 = 8690788
389 + 8690399 = 8690788
401 + 8690387 = 8690788
521 + 8690267 = 8690788

Showing the first eight; more decompositions exist.
