Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019880, here are decompositions:

7 + 1019873 = 1019880
19 + 1019861 = 1019880
23 + 1019857 = 1019880
31 + 1019849 = 1019880
41 + 1019839 = 1019880
53 + 1019827 = 1019880
61 + 1019819 = 1019880
79 + 1019801 = 1019880

Showing the first eight; more decompositions exist.
