Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057666, here are decompositions:

3 + 1057663 = 1057666
23 + 1057643 = 1057666
53 + 1057613 = 1057666
59 + 1057607 = 1057666
89 + 1057577 = 1057666
173 + 1057493 = 1057666
179 + 1057487 = 1057666
359 + 1057307 = 1057666

Showing the first eight; more decompositions exist.
