Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057520, here are decompositions:

31 + 1057489 = 1057520
43 + 1057477 = 1057520
109 + 1057411 = 1057520
127 + 1057393 = 1057520
229 + 1057291 = 1057520
241 + 1057279 = 1057520
271 + 1057249 = 1057520
283 + 1057237 = 1057520

Showing the first eight; more decompositions exist.
