Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057420, here are decompositions:

29 + 1057391 = 1057420
53 + 1057367 = 1057420
59 + 1057361 = 1057420
113 + 1057307 = 1057420
149 + 1057271 = 1057420
197 + 1057223 = 1057420
239 + 1057181 = 1057420
257 + 1057163 = 1057420

Showing the first eight; more decompositions exist.
