Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663144, here are decompositions:

43 + 8663101 = 8663144
73 + 8663071 = 8663144
157 + 8662987 = 8663144
181 + 8662963 = 8663144
277 + 8662867 = 8663144
313 + 8662831 = 8663144
337 + 8662807 = 8663144
397 + 8662747 = 8663144

Showing the first eight; more decompositions exist.
