Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724044, here are decompositions:

31 + 8724013 = 8724044
67 + 8723977 = 8724044
97 + 8723947 = 8724044
151 + 8723893 = 8724044
157 + 8723887 = 8724044
193 + 8723851 = 8724044
211 + 8723833 = 8724044
223 + 8723821 = 8724044

Showing the first eight; more decompositions exist.
