Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999654, here are decompositions:

23 + 999631 = 999654
31 + 999623 = 999654
41 + 999613 = 999654
43 + 999611 = 999654
101 + 999553 = 999654
113 + 999541 = 999654
163 + 999491 = 999654
223 + 999431 = 999654

Showing the first eight; more decompositions exist.
