Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747072, here are decompositions:

31 + 8747041 = 8747072
73 + 8746999 = 8747072
109 + 8746963 = 8747072
151 + 8746921 = 8747072
193 + 8746879 = 8747072
199 + 8746873 = 8747072
211 + 8746861 = 8747072
223 + 8746849 = 8747072

Showing the first eight; more decompositions exist.
