Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018808, here are decompositions:

19 + 1018789 = 1018808
31 + 1018777 = 1018808
79 + 1018729 = 1018808
97 + 1018711 = 1018808
139 + 1018669 = 1018808
157 + 1018651 = 1018808
331 + 1018477 = 1018808
337 + 1018471 = 1018808

Showing the first eight; more decompositions exist.
