Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018874, here are decompositions:

61 + 1018813 = 1018874
67 + 1018807 = 1018874
97 + 1018777 = 1018874
163 + 1018711 = 1018874
223 + 1018651 = 1018874
331 + 1018543 = 1018874
397 + 1018477 = 1018874
463 + 1018411 = 1018874

Showing the first eight; more decompositions exist.
