Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057240, here are decompositions:

3 + 1057237 = 1057240
17 + 1057223 = 1057240
59 + 1057181 = 1057240
83 + 1057157 = 1057240
227 + 1057013 = 1057240
269 + 1056971 = 1057240
281 + 1056959 = 1057240
311 + 1056929 = 1057240

Showing the first eight; more decompositions exist.
