Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018620, here are decompositions:

7 + 1018613 = 1018620
37 + 1018583 = 1018620
61 + 1018559 = 1018620
107 + 1018513 = 1018620
131 + 1018489 = 1018620
149 + 1018471 = 1018620
173 + 1018447 = 1018620
181 + 1018439 = 1018620

Showing the first eight; more decompositions exist.
