Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690458, here are decompositions:

5 + 8690453 = 8690458
47 + 8690411 = 8690458
59 + 8690399 = 8690458
71 + 8690387 = 8690458
107 + 8690351 = 8690458
167 + 8690291 = 8690458
191 + 8690267 = 8690458
281 + 8690177 = 8690458

Showing the first eight; more decompositions exist.
