Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998512, here are decompositions:

41 + 998471 = 998512
83 + 998429 = 998512
89 + 998423 = 998512
101 + 998411 = 998512
113 + 998399 = 998512
131 + 998381 = 998512
239 + 998273 = 998512
269 + 998243 = 998512

Showing the first eight; more decompositions exist.
