Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018814, here are decompositions:

3 + 1018811 = 1018814
7 + 1018807 = 1018814
37 + 1018777 = 1018814
103 + 1018711 = 1018814
163 + 1018651 = 1018814
193 + 1018621 = 1018814
271 + 1018543 = 1018814
337 + 1018477 = 1018814

Showing the first eight; more decompositions exist.
