Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640554, here are decompositions:

7 + 8640547 = 8640554
61 + 8640493 = 8640554
73 + 8640481 = 8640554
103 + 8640451 = 8640554
127 + 8640427 = 8640554
163 + 8640391 = 8640554
313 + 8640241 = 8640554
367 + 8640187 = 8640554

Showing the first eight; more decompositions exist.
