Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653942, here are decompositions:

5 + 8653937 = 8653942
53 + 8653889 = 8653942
83 + 8653859 = 8653942
131 + 8653811 = 8653942
173 + 8653769 = 8653942
179 + 8653763 = 8653942
233 + 8653709 = 8653942
239 + 8653703 = 8653942

Showing the first eight; more decompositions exist.
