Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002398, here are decompositions:

37 + 1002361 = 1002398
109 + 1002289 = 1002398
139 + 1002259 = 1002398
151 + 1002247 = 1002398
157 + 1002241 = 1002398
277 + 1002121 = 1002398
307 + 1002091 = 1002398
337 + 1002061 = 1002398

Showing the first eight; more decompositions exist.
