Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677478, here are decompositions:

79 + 8677399 = 8677478
181 + 8677297 = 8677478
211 + 8677267 = 8677478
307 + 8677171 = 8677478
421 + 8677057 = 8677478
487 + 8676991 = 8677478
541 + 8676937 = 8677478
631 + 8676847 = 8677478

Showing the first eight; more decompositions exist.
