Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690818, here are decompositions:

5 + 8690813 = 8690818
29 + 8690789 = 8690818
179 + 8690639 = 8690818
251 + 8690567 = 8690818
419 + 8690399 = 8690818
431 + 8690387 = 8690818
467 + 8690351 = 8690818
641 + 8690177 = 8690818

Showing the first eight; more decompositions exist.
