Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755842, here are decompositions:

19 + 8755823 = 8755842
23 + 8755819 = 8755842
31 + 8755811 = 8755842
61 + 8755781 = 8755842
101 + 8755741 = 8755842
113 + 8755729 = 8755842
131 + 8755711 = 8755842
223 + 8755619 = 8755842

Showing the first eight; more decompositions exist.
