Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643554, here are decompositions:

67 + 8643487 = 8643554
97 + 8643457 = 8643554
211 + 8643343 = 8643554
331 + 8643223 = 8643554
373 + 8643181 = 8643554
421 + 8643133 = 8643554
433 + 8643121 = 8643554
463 + 8643091 = 8643554

Showing the first eight; more decompositions exist.
