Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690786, here are decompositions:

3 + 8690783 = 8690786
19 + 8690767 = 8690786
73 + 8690713 = 8690786
103 + 8690683 = 8690786
109 + 8690677 = 8690786
127 + 8690659 = 8690786
193 + 8690593 = 8690786
229 + 8690557 = 8690786

Showing the first eight; more decompositions exist.
