Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990122, here are decompositions:

79 + 990043 = 990122
109 + 990013 = 990122
151 + 989971 = 990122
163 + 989959 = 990122
193 + 989929 = 990122
283 + 989839 = 990122
373 + 989749 = 990122
379 + 989743 = 990122

Showing the first eight; more decompositions exist.
