Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751942, here are decompositions:

11 + 8751931 = 8751942
71 + 8751871 = 8751942
79 + 8751863 = 8751942
83 + 8751859 = 8751942
103 + 8751839 = 8751942
113 + 8751829 = 8751942
139 + 8751803 = 8751942
193 + 8751749 = 8751942

Showing the first eight; more decompositions exist.
