Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664518, here are decompositions:

67 + 8664451 = 8664518
97 + 8664421 = 8664518
151 + 8664367 = 8664518
337 + 8664181 = 8664518
409 + 8664109 = 8664518
619 + 8663899 = 8664518
691 + 8663827 = 8664518
997 + 8663521 = 8664518

Showing the first eight; more decompositions exist.
