Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690370, here are decompositions:

11 + 8690359 = 8690370
19 + 8690351 = 8690370
37 + 8690333 = 8690370
53 + 8690317 = 8690370
67 + 8690303 = 8690370
79 + 8690291 = 8690370
103 + 8690267 = 8690370
149 + 8690221 = 8690370

Showing the first eight; more decompositions exist.
