Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042394, here are decompositions:

13 + 1042381 = 1042394
37 + 1042357 = 1042394
61 + 1042333 = 1042394
127 + 1042267 = 1042394
151 + 1042243 = 1042394
211 + 1042183 = 1042394
271 + 1042123 = 1042394
307 + 1042087 = 1042394

Showing the first eight; more decompositions exist.
