Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690724, here are decompositions:

11 + 8690713 = 8690724
41 + 8690683 = 8690724
47 + 8690677 = 8690724
61 + 8690663 = 8690724
113 + 8690611 = 8690724
131 + 8690593 = 8690724
157 + 8690567 = 8690724
167 + 8690557 = 8690724

Showing the first eight; more decompositions exist.
