Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990598, here are decompositions:

5 + 990593 = 990598
101 + 990497 = 990598
227 + 990371 = 990598
239 + 990359 = 990598
269 + 990329 = 990598
311 + 990287 = 990598
317 + 990281 = 990598
359 + 990239 = 990598

Showing the first eight; more decompositions exist.
