Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751180, here are decompositions:

7 + 8751173 = 8751180
23 + 8751157 = 8751180
29 + 8751151 = 8751180
37 + 8751143 = 8751180
41 + 8751139 = 8751180
79 + 8751101 = 8751180
83 + 8751097 = 8751180
89 + 8751091 = 8751180

Showing the first eight; more decompositions exist.
