Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747148, here are decompositions:

29 + 8747119 = 8747148
37 + 8747111 = 8747148
107 + 8747041 = 8747148
149 + 8746999 = 8747148
181 + 8746967 = 8747148
191 + 8746957 = 8747148
199 + 8746949 = 8747148
211 + 8746937 = 8747148

Showing the first eight; more decompositions exist.
