Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22878, here are decompositions:

7 + 22871 = 22878
17 + 22861 = 22878
19 + 22859 = 22878
61 + 22817 = 22878
67 + 22811 = 22878
71 + 22807 = 22878
101 + 22777 = 22878
109 + 22769 = 22878

Showing the first eight; more decompositions exist.
