Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044878, here are decompositions:

19 + 1044859 = 1044878
31 + 1044847 = 1044878
67 + 1044811 = 1044878
97 + 1044781 = 1044878
127 + 1044751 = 1044878
139 + 1044739 = 1044878
151 + 1044727 = 1044878
181 + 1044697 = 1044878

Showing the first eight; more decompositions exist.
