Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751248, here are decompositions:

67 + 8751181 = 8751248
97 + 8751151 = 8751248
109 + 8751139 = 8751248
151 + 8751097 = 8751248
157 + 8751091 = 8751248
211 + 8751037 = 8751248
241 + 8751007 = 8751248
307 + 8750941 = 8751248

Showing the first eight; more decompositions exist.
