Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990210, here are decompositions:

29 + 990181 = 990210
31 + 990179 = 990210
41 + 990169 = 990210
47 + 990163 = 990210
59 + 990151 = 990210
73 + 990137 = 990210
157 + 990053 = 990210
167 + 990043 = 990210

Showing the first eight; more decompositions exist.
