Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724030, here are decompositions:

17 + 8724013 = 8724030
37 + 8723993 = 8724030
43 + 8723987 = 8724030
53 + 8723977 = 8724030
79 + 8723951 = 8724030
83 + 8723947 = 8724030
97 + 8723933 = 8724030
101 + 8723929 = 8724030

Showing the first eight; more decompositions exist.
