Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640044, here are decompositions:

31 + 8640013 = 8640044
43 + 8640001 = 8640044
67 + 8639977 = 8640044
181 + 8639863 = 8640044
241 + 8639803 = 8640044
271 + 8639773 = 8640044
331 + 8639713 = 8640044
397 + 8639647 = 8640044

Showing the first eight; more decompositions exist.
