Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761140, here are decompositions:

7 + 8761133 = 8761140
23 + 8761117 = 8761140
41 + 8761099 = 8761140
61 + 8761079 = 8761140
103 + 8761037 = 8761140
131 + 8761009 = 8761140
149 + 8760991 = 8761140
163 + 8760977 = 8761140

Showing the first eight; more decompositions exist.
