Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675978, here are decompositions:

67 + 8675911 = 8675978
109 + 8675869 = 8675978
139 + 8675839 = 8675978
211 + 8675767 = 8675978
229 + 8675749 = 8675978
307 + 8675671 = 8675978
457 + 8675521 = 8675978
601 + 8675377 = 8675978

Showing the first eight; more decompositions exist.
