Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751940, here are decompositions:

53 + 8751887 = 8751940
101 + 8751839 = 8751940
137 + 8751803 = 8751940
167 + 8751773 = 8751940
173 + 8751767 = 8751940
191 + 8751749 = 8751940
269 + 8751671 = 8751940
311 + 8751629 = 8751940

Showing the first eight; more decompositions exist.
