Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998626, here are decompositions:

3 + 998623 = 998626
89 + 998537 = 998626
113 + 998513 = 998626
197 + 998429 = 998626
227 + 998399 = 998626
353 + 998273 = 998626
383 + 998243 = 998626
389 + 998237 = 998626

Showing the first eight; more decompositions exist.
