Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747124, here are decompositions:

5 + 8747119 = 8747124
13 + 8747111 = 8747124
31 + 8747093 = 8747124
41 + 8747083 = 8747124
53 + 8747071 = 8747124
83 + 8747041 = 8747124
157 + 8746967 = 8747124
167 + 8746957 = 8747124

Showing the first eight; more decompositions exist.
