Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990152, here are decompositions:

109 + 990043 = 990152
139 + 990013 = 990152
151 + 990001 = 990152
181 + 989971 = 990152
193 + 989959 = 990152
223 + 989929 = 990152
283 + 989869 = 990152
313 + 989839 = 990152

Showing the first eight; more decompositions exist.
