Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999668, here are decompositions:

37 + 999631 = 999668
127 + 999541 = 999668
139 + 999529 = 999668
337 + 999331 = 999668
487 + 999181 = 999668
499 + 999169 = 999668
577 + 999091 = 999668
601 + 999067 = 999668

Showing the first eight; more decompositions exist.
