Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670778, here are decompositions:

5 + 8670773 = 8670778
167 + 8670611 = 8670778
227 + 8670551 = 8670778
269 + 8670509 = 8670778
521 + 8670257 = 8670778
587 + 8670191 = 8670778
797 + 8669981 = 8670778
839 + 8669939 = 8670778

Showing the first eight; more decompositions exist.
