Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002390, here are decompositions:

13 + 1002377 = 1002390
29 + 1002361 = 1002390
31 + 1002359 = 1002390
41 + 1002349 = 1002390
43 + 1002347 = 1002390
47 + 1002343 = 1002390
101 + 1002289 = 1002390
127 + 1002263 = 1002390

Showing the first eight; more decompositions exist.
