Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018904, here are decompositions:

31 + 1018873 = 1018904
97 + 1018807 = 1018904
127 + 1018777 = 1018904
193 + 1018711 = 1018904
283 + 1018621 = 1018904
433 + 1018471 = 1018904
457 + 1018447 = 1018904
547 + 1018357 = 1018904

Showing the first eight; more decompositions exist.
