Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679490, here are decompositions:

41 + 8679449 = 8679490
137 + 8679353 = 8679490
179 + 8679311 = 8679490
269 + 8679221 = 8679490
311 + 8679179 = 8679490
353 + 8679137 = 8679490
419 + 8679071 = 8679490
431 + 8679059 = 8679490

Showing the first eight; more decompositions exist.
