Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998620, here are decompositions:

3 + 998617 = 998620
59 + 998561 = 998620
83 + 998537 = 998620
107 + 998513 = 998620
149 + 998471 = 998620
191 + 998429 = 998620
197 + 998423 = 998620
239 + 998381 = 998620

Showing the first eight; more decompositions exist.
