Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679290, here are decompositions:

13 + 8679277 = 8679290
19 + 8679271 = 8679290
73 + 8679217 = 8679290
97 + 8679193 = 8679290
181 + 8679109 = 8679290
211 + 8679079 = 8679290
349 + 8678941 = 8679290
397 + 8678893 = 8679290

Showing the first eight; more decompositions exist.
