Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690406, here are decompositions:

7 + 8690399 = 8690406
19 + 8690387 = 8690406
29 + 8690377 = 8690406
47 + 8690359 = 8690406
73 + 8690333 = 8690406
89 + 8690317 = 8690406
103 + 8690303 = 8690406
113 + 8690293 = 8690406

Showing the first eight; more decompositions exist.
