Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690446, here are decompositions:

47 + 8690399 = 8690446
59 + 8690387 = 8690446
113 + 8690333 = 8690446
179 + 8690267 = 8690446
269 + 8690177 = 8690446
353 + 8690093 = 8690446
383 + 8690063 = 8690446
449 + 8689997 = 8690446

Showing the first eight; more decompositions exist.
