Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761172, here are decompositions:

3 + 8761169 = 8761172
19 + 8761153 = 8761172
31 + 8761141 = 8761172
73 + 8761099 = 8761172
163 + 8761009 = 8761172
181 + 8760991 = 8761172
271 + 8760901 = 8761172
373 + 8760799 = 8761172

Showing the first eight; more decompositions exist.
