Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057742, here are decompositions:

3 + 1057739 = 1057742
43 + 1057699 = 1057742
61 + 1057681 = 1057742
79 + 1057663 = 1057742
109 + 1057633 = 1057742
139 + 1057603 = 1057742
163 + 1057579 = 1057742
181 + 1057561 = 1057742

Showing the first eight; more decompositions exist.
