Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019844, here are decompositions:

5 + 1019839 = 1019844
17 + 1019827 = 1019844
43 + 1019801 = 1019844
61 + 1019783 = 1019844
73 + 1019771 = 1019844
97 + 1019747 = 1019844
103 + 1019741 = 1019844
113 + 1019731 = 1019844

Showing the first eight; more decompositions exist.
