Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690450, here are decompositions:

37 + 8690413 = 8690450
73 + 8690377 = 8690450
79 + 8690371 = 8690450
157 + 8690293 = 8690450
229 + 8690221 = 8690450
277 + 8690173 = 8690450
331 + 8690119 = 8690450
409 + 8690041 = 8690450

Showing the first eight; more decompositions exist.
