Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690464, here are decompositions:

11 + 8690453 = 8690464
53 + 8690411 = 8690464
113 + 8690351 = 8690464
131 + 8690333 = 8690464
173 + 8690291 = 8690464
197 + 8690267 = 8690464
347 + 8690117 = 8690464
401 + 8690063 = 8690464

Showing the first eight; more decompositions exist.
