Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679742, here are decompositions:

3 + 8679739 = 8679742
101 + 8679641 = 8679742
191 + 8679551 = 8679742
293 + 8679449 = 8679742
389 + 8679353 = 8679742
431 + 8679311 = 8679742
521 + 8679221 = 8679742
563 + 8679179 = 8679742

Showing the first eight; more decompositions exist.
