Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999812, here are decompositions:

3 + 999809 = 999812
43 + 999769 = 999812
181 + 999631 = 999812
199 + 999613 = 999812
271 + 999541 = 999812
283 + 999529 = 999812
313 + 999499 = 999812
379 + 999433 = 999812

Showing the first eight; more decompositions exist.
