Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690554, here are decompositions:

3 + 8690551 = 8690554
23 + 8690531 = 8690554
101 + 8690453 = 8690554
167 + 8690387 = 8690554
251 + 8690303 = 8690554
263 + 8690291 = 8690554
461 + 8690093 = 8690554
491 + 8690063 = 8690554

Showing the first eight; more decompositions exist.
