Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007878, here are decompositions:

5 + 1007873 = 1007878
17 + 1007861 = 1007878
59 + 1007819 = 1007878
71 + 1007807 = 1007878
89 + 1007789 = 1007878
107 + 1007771 = 1007878
149 + 1007729 = 1007878
167 + 1007711 = 1007878

Showing the first eight; more decompositions exist.
