Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624878, here are decompositions:

5 + 8624873 = 8624878
71 + 8624807 = 8624878
107 + 8624771 = 8624878
257 + 8624621 = 8624878
401 + 8624477 = 8624878
419 + 8624459 = 8624878
641 + 8624237 = 8624878
677 + 8624201 = 8624878

Showing the first eight; more decompositions exist.
