Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727230, here are decompositions:

19 + 8727211 = 8727230
67 + 8727163 = 8727230
73 + 8727157 = 8727230
139 + 8727091 = 8727230
163 + 8727067 = 8727230
181 + 8727049 = 8727230
199 + 8727031 = 8727230
241 + 8726989 = 8727230

Showing the first eight; more decompositions exist.
