Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724012, here are decompositions:

19 + 8723993 = 8724012
61 + 8723951 = 8724012
79 + 8723933 = 8724012
83 + 8723929 = 8724012
103 + 8723909 = 8724012
109 + 8723903 = 8724012
113 + 8723899 = 8724012
179 + 8723833 = 8724012

Showing the first eight; more decompositions exist.
