Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663942, here are decompositions:

19 + 8663923 = 8663942
43 + 8663899 = 8663942
73 + 8663869 = 8663942
139 + 8663803 = 8663942
223 + 8663719 = 8663942
241 + 8663701 = 8663942
349 + 8663593 = 8663942
421 + 8663521 = 8663942

Showing the first eight; more decompositions exist.
