Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031666, here are decompositions:

37 + 1031629 = 1031666
43 + 1031623 = 1031666
73 + 1031593 = 1031666
367 + 1031299 = 1031666
547 + 1031119 = 1031666
613 + 1031053 = 1031666
619 + 1031047 = 1031666
673 + 1030993 = 1031666

Showing the first eight; more decompositions exist.
