Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005554, here are decompositions:

3 + 1005551 = 1005554
13 + 1005541 = 1005554
61 + 1005493 = 1005554
73 + 1005481 = 1005554
97 + 1005457 = 1005554
127 + 1005427 = 1005554
163 + 1005391 = 1005554
181 + 1005373 = 1005554

Showing the first eight; more decompositions exist.
