Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018586, here are decompositions:

3 + 1018583 = 1018586
43 + 1018543 = 1018586
73 + 1018513 = 1018586
97 + 1018489 = 1018586
109 + 1018477 = 1018586
139 + 1018447 = 1018586
157 + 1018429 = 1018586
229 + 1018357 = 1018586

Showing the first eight; more decompositions exist.
