Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663378, here are decompositions:

67 + 8663311 = 8663378
277 + 8663101 = 8663378
307 + 8663071 = 8663378
439 + 8662939 = 8663378
487 + 8662891 = 8663378
547 + 8662831 = 8663378
571 + 8662807 = 8663378
631 + 8662747 = 8663378

Showing the first eight; more decompositions exist.
