Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655942, here are decompositions:

5 + 8655937 = 8655942
19 + 8655923 = 8655942
23 + 8655919 = 8655942
41 + 8655901 = 8655942
59 + 8655883 = 8655942
73 + 8655869 = 8655942
83 + 8655859 = 8655942
101 + 8655841 = 8655942

Showing the first eight; more decompositions exist.
