Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679442, here are decompositions:

89 + 8679353 = 8679442
131 + 8679311 = 8679442
263 + 8679179 = 8679442
383 + 8679059 = 8679442
479 + 8678963 = 8679442
491 + 8678951 = 8679442
503 + 8678939 = 8679442
509 + 8678933 = 8679442

Showing the first eight; more decompositions exist.
