Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012388, here are decompositions:

19 + 1012369 = 1012388
67 + 1012321 = 1012388
109 + 1012279 = 1012388
127 + 1012261 = 1012388
199 + 1012189 = 1012388
229 + 1012159 = 1012388
241 + 1012147 = 1012388
379 + 1012009 = 1012388

Showing the first eight; more decompositions exist.
