Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018548, here are decompositions:

5 + 1018543 = 1018548
59 + 1018489 = 1018548
71 + 1018477 = 1018548
101 + 1018447 = 1018548
109 + 1018439 = 1018548
127 + 1018421 = 1018548
137 + 1018411 = 1018548
191 + 1018357 = 1018548

Showing the first eight; more decompositions exist.
