Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752040, here are decompositions:

7 + 8752033 = 8752040
67 + 8751973 = 8752040
109 + 8751931 = 8752040
181 + 8751859 = 8752040
211 + 8751829 = 8752040
223 + 8751817 = 8752040
307 + 8751733 = 8752040
313 + 8751727 = 8752040

Showing the first eight; more decompositions exist.
