Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025388, here are decompositions:

5 + 1025383 = 1025388
37 + 1025351 = 1025388
41 + 1025347 = 1025388
61 + 1025327 = 1025388
107 + 1025281 = 1025388
109 + 1025279 = 1025388
127 + 1025261 = 1025388
131 + 1025257 = 1025388

Showing the first eight; more decompositions exist.
