Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990184, here are decompositions:

3 + 990181 = 990184
5 + 990179 = 990184
47 + 990137 = 990184
131 + 990053 = 990184
233 + 989951 = 990184
263 + 989921 = 990184
311 + 989873 = 990184
347 + 989837 = 990184

Showing the first eight; more decompositions exist.
