Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724066, here are decompositions:

53 + 8724013 = 8724066
73 + 8723993 = 8724066
79 + 8723987 = 8724066
89 + 8723977 = 8724066
137 + 8723929 = 8724066
157 + 8723909 = 8724066
163 + 8723903 = 8724066
167 + 8723899 = 8724066

Showing the first eight; more decompositions exist.
