Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724024, here are decompositions:

11 + 8724013 = 8724024
31 + 8723993 = 8724024
37 + 8723987 = 8724024
47 + 8723977 = 8724024
73 + 8723951 = 8724024
103 + 8723921 = 8724024
131 + 8723893 = 8724024
137 + 8723887 = 8724024

Showing the first eight; more decompositions exist.
