Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990206, here are decompositions:

37 + 990169 = 990206
43 + 990163 = 990206
163 + 990043 = 990206
193 + 990013 = 990206
229 + 989977 = 990206
277 + 989929 = 990206
337 + 989869 = 990206
367 + 989839 = 990206

Showing the first eight; more decompositions exist.
