Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986380, here are decompositions:

11 + 986369 = 986380
29 + 986351 = 986380
41 + 986339 = 986380
47 + 986333 = 986380
113 + 986267 = 986380
167 + 986213 = 986380
173 + 986207 = 986380
191 + 986189 = 986380

Showing the first eight; more decompositions exist.
