Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667478, here are decompositions:

47 + 8667431 = 8667478
59 + 8667419 = 8667478
101 + 8667377 = 8667478
107 + 8667371 = 8667478
179 + 8667299 = 8667478
251 + 8667227 = 8667478
311 + 8667167 = 8667478
587 + 8666891 = 8667478

Showing the first eight; more decompositions exist.
