Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751120, here are decompositions:

19 + 8751101 = 8751120
23 + 8751097 = 8751120
29 + 8751091 = 8751120
31 + 8751089 = 8751120
41 + 8751079 = 8751120
83 + 8751037 = 8751120
107 + 8751013 = 8751120
113 + 8751007 = 8751120

Showing the first eight; more decompositions exist.
