Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057878, here are decompositions:

47 + 1057831 = 1057878
71 + 1057807 = 1057878
97 + 1057781 = 1057878
137 + 1057741 = 1057878
139 + 1057739 = 1057878
179 + 1057699 = 1057878
197 + 1057681 = 1057878
271 + 1057607 = 1057878

Showing the first eight; more decompositions exist.
