Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690398, here are decompositions:

11 + 8690387 = 8690398
47 + 8690351 = 8690398
107 + 8690291 = 8690398
131 + 8690267 = 8690398
281 + 8690117 = 8690398
401 + 8689997 = 8690398
419 + 8689979 = 8690398
449 + 8689949 = 8690398

Showing the first eight; more decompositions exist.
