Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002272, here are decompositions:

13 + 1002259 = 1002272
31 + 1002241 = 1002272
151 + 1002121 = 1002272
163 + 1002109 = 1002272
181 + 1002091 = 1002272
199 + 1002073 = 1002272
211 + 1002061 = 1002272
223 + 1002049 = 1002272

Showing the first eight; more decompositions exist.
