Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701878, here are decompositions:

5 + 8701873 = 8701878
7 + 8701871 = 8701878
67 + 8701811 = 8701878
89 + 8701789 = 8701878
131 + 8701747 = 8701878
137 + 8701741 = 8701878
149 + 8701729 = 8701878
257 + 8701621 = 8701878

Showing the first eight; more decompositions exist.
