Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018670, here are decompositions:

19 + 1018651 = 1018670
127 + 1018543 = 1018670
157 + 1018513 = 1018670
181 + 1018489 = 1018670
193 + 1018477 = 1018670
199 + 1018471 = 1018670
223 + 1018447 = 1018670
241 + 1018429 = 1018670

Showing the first eight; more decompositions exist.
