Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990346, here are decompositions:

17 + 990329 = 990346
23 + 990323 = 990346
53 + 990293 = 990346
59 + 990287 = 990346
107 + 990239 = 990346
167 + 990179 = 990346
293 + 990053 = 990346
347 + 989999 = 990346

Showing the first eight; more decompositions exist.
