Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002388, here are decompositions:

11 + 1002377 = 1002388
29 + 1002359 = 1002388
41 + 1002347 = 1002388
47 + 1002341 = 1002388
89 + 1002299 = 1002388
131 + 1002257 = 1002388
197 + 1002191 = 1002388
239 + 1002149 = 1002388

Showing the first eight; more decompositions exist.
