Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747238, here are decompositions:

47 + 8747191 = 8747238
67 + 8747171 = 8747238
79 + 8747159 = 8747238
127 + 8747111 = 8747238
167 + 8747071 = 8747238
197 + 8747041 = 8747238
239 + 8746999 = 8747238
271 + 8746967 = 8747238

Showing the first eight; more decompositions exist.
