Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8614978, here are decompositions:

5 + 8614973 = 8614978
11 + 8614967 = 8614978
89 + 8614889 = 8614978
137 + 8614841 = 8614978
149 + 8614829 = 8614978
191 + 8614787 = 8614978
431 + 8614547 = 8614978
461 + 8614517 = 8614978

Showing the first eight; more decompositions exist.
