Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643546, here are decompositions:

7 + 8643539 = 8643546
19 + 8643527 = 8643546
59 + 8643487 = 8643546
89 + 8643457 = 8643546
103 + 8643443 = 8643546
113 + 8643433 = 8643546
137 + 8643409 = 8643546
179 + 8643367 = 8643546

Showing the first eight; more decompositions exist.
