Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042418, here are decompositions:

19 + 1042399 = 1042418
37 + 1042381 = 1042418
61 + 1042357 = 1042418
109 + 1042309 = 1042418
151 + 1042267 = 1042418
277 + 1042141 = 1042418
331 + 1042087 = 1042418
337 + 1042081 = 1042418

Showing the first eight; more decompositions exist.
