Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743040, here are decompositions:

3 + 8743037 = 8743040
13 + 8743027 = 8743040
43 + 8742997 = 8743040
67 + 8742973 = 8743040
109 + 8742931 = 8743040
193 + 8742847 = 8743040
223 + 8742817 = 8743040
367 + 8742673 = 8743040

Showing the first eight; more decompositions exist.
