Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679642, here are decompositions:

61 + 8679581 = 8679642
113 + 8679529 = 8679642
193 + 8679449 = 8679642
263 + 8679379 = 8679642
269 + 8679373 = 8679642
331 + 8679311 = 8679642
353 + 8679289 = 8679642
421 + 8679221 = 8679642

Showing the first eight; more decompositions exist.
