Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018626, here are decompositions:

5 + 1018621 = 1018626
13 + 1018613 = 1018626
43 + 1018583 = 1018626
67 + 1018559 = 1018626
83 + 1018543 = 1018626
113 + 1018513 = 1018626
137 + 1018489 = 1018626
149 + 1018477 = 1018626

Showing the first eight; more decompositions exist.
