Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690944, here are decompositions:

23 + 8690921 = 8690944
131 + 8690813 = 8690944
281 + 8690663 = 8690944
467 + 8690477 = 8690944
491 + 8690453 = 8690944
557 + 8690387 = 8690944
593 + 8690351 = 8690944
641 + 8690303 = 8690944

Showing the first eight; more decompositions exist.
