Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751278, here are decompositions:

97 + 8751181 = 8751278
127 + 8751151 = 8751278
139 + 8751139 = 8751278
181 + 8751097 = 8751278
199 + 8751079 = 8751278
241 + 8751037 = 8751278
271 + 8751007 = 8751278
331 + 8750947 = 8751278

Showing the first eight; more decompositions exist.
