Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005558, here are decompositions:

5 + 1005553 = 1005558
7 + 1005551 = 1005558
17 + 1005541 = 1005558
31 + 1005527 = 1005558
101 + 1005457 = 1005558
131 + 1005427 = 1005558
149 + 1005409 = 1005558
167 + 1005391 = 1005558

Showing the first eight; more decompositions exist.
