Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660978, here are decompositions:

31 + 8660947 = 8660978
181 + 8660797 = 8660978
211 + 8660767 = 8660978
307 + 8660671 = 8660978
367 + 8660611 = 8660978
409 + 8660569 = 8660978
439 + 8660539 = 8660978
541 + 8660437 = 8660978

Showing the first eight; more decompositions exist.
