Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999724, here are decompositions:

3 + 999721 = 999724
41 + 999683 = 999724
53 + 999671 = 999724
71 + 999653 = 999724
101 + 999623 = 999724
113 + 999611 = 999724
233 + 999491 = 999724
293 + 999431 = 999724

Showing the first eight; more decompositions exist.
