Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048420, here are decompositions:

29 + 1048391 = 1048420
53 + 1048367 = 1048420
59 + 1048361 = 1048420
227 + 1048193 = 1048420
281 + 1048139 = 1048420
293 + 1048127 = 1048420
431 + 1047989 = 1048420
449 + 1047971 = 1048420

Showing the first eight; more decompositions exist.
