Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990158, here are decompositions:

7 + 990151 = 990158
157 + 990001 = 990158
181 + 989977 = 990158
199 + 989959 = 990158
229 + 989929 = 990158
241 + 989917 = 990158
271 + 989887 = 990158
331 + 989827 = 990158

Showing the first eight; more decompositions exist.
