Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057720, here are decompositions:

17 + 1057703 = 1057720
89 + 1057631 = 1057720
107 + 1057613 = 1057720
113 + 1057607 = 1057720
179 + 1057541 = 1057720
227 + 1057493 = 1057720
233 + 1057487 = 1057720
353 + 1057367 = 1057720

Showing the first eight; more decompositions exist.
