Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761380, here are decompositions:

41 + 8761339 = 8761380
53 + 8761327 = 8761380
83 + 8761297 = 8761380
101 + 8761279 = 8761380
127 + 8761253 = 8761380
137 + 8761243 = 8761380
167 + 8761213 = 8761380
211 + 8761169 = 8761380

Showing the first eight; more decompositions exist.
