Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648072, here are decompositions:

79 + 8647993 = 8648072
109 + 8647963 = 8648072
193 + 8647879 = 8648072
271 + 8647801 = 8648072
313 + 8647759 = 8648072
373 + 8647699 = 8648072
541 + 8647531 = 8648072
571 + 8647501 = 8648072

Showing the first eight; more decompositions exist.
