Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727378, here are decompositions:

19 + 8727359 = 8727378
29 + 8727349 = 8727378
61 + 8727317 = 8727378
109 + 8727269 = 8727378
131 + 8727247 = 8727378
167 + 8727211 = 8727378
181 + 8727197 = 8727378
199 + 8727179 = 8727378

Showing the first eight; more decompositions exist.
