Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691942, here are decompositions:

5 + 8691937 = 8691942
19 + 8691923 = 8691942
41 + 8691901 = 8691942
53 + 8691889 = 8691942
59 + 8691883 = 8691942
89 + 8691853 = 8691942
109 + 8691833 = 8691942
139 + 8691803 = 8691942

Showing the first eight; more decompositions exist.
