Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999662, here are decompositions:

31 + 999631 = 999662
109 + 999553 = 999662
163 + 999499 = 999662
211 + 999451 = 999662
229 + 999433 = 999662
331 + 999331 = 999662
463 + 999199 = 999662
571 + 999091 = 999662

Showing the first eight; more decompositions exist.
