Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690394, here are decompositions:

7 + 8690387 = 8690394
17 + 8690377 = 8690394
23 + 8690371 = 8690394
43 + 8690351 = 8690394
61 + 8690333 = 8690394
101 + 8690293 = 8690394
103 + 8690291 = 8690394
127 + 8690267 = 8690394

Showing the first eight; more decompositions exist.
