Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751984, here are decompositions:

11 + 8751973 = 8751984
53 + 8751931 = 8751984
97 + 8751887 = 8751984
113 + 8751871 = 8751984
167 + 8751817 = 8751984
181 + 8751803 = 8751984
211 + 8751773 = 8751984
251 + 8751733 = 8751984

Showing the first eight; more decompositions exist.
