Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018550, here are decompositions:

7 + 1018543 = 1018550
37 + 1018513 = 1018550
61 + 1018489 = 1018550
73 + 1018477 = 1018550
79 + 1018471 = 1018550
103 + 1018447 = 1018550
139 + 1018411 = 1018550
193 + 1018357 = 1018550

Showing the first eight; more decompositions exist.
