Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998782, here are decompositions:

3 + 998779 = 998782
23 + 998759 = 998782
101 + 998681 = 998782
131 + 998651 = 998782
149 + 998633 = 998782
269 + 998513 = 998782
311 + 998471 = 998782
353 + 998429 = 998782

Showing the first eight; more decompositions exist.
