Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998590, here are decompositions:

29 + 998561 = 998590
53 + 998537 = 998590
167 + 998423 = 998590
179 + 998411 = 998590
191 + 998399 = 998590
317 + 998273 = 998590
347 + 998243 = 998590
353 + 998237 = 998590

Showing the first eight; more decompositions exist.
