Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988654, here are decompositions:

3 + 988651 = 988654
5 + 988649 = 988654
11 + 988643 = 988654
47 + 988607 = 988654
71 + 988583 = 988654
83 + 988571 = 988654
113 + 988541 = 988654
311 + 988343 = 988654

Showing the first eight; more decompositions exist.
