Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990260, here are decompositions:

79 + 990181 = 990260
97 + 990163 = 990260
109 + 990151 = 990260
223 + 990037 = 990260
283 + 989977 = 990260
331 + 989929 = 990260
373 + 989887 = 990260
421 + 989839 = 990260

Showing the first eight; more decompositions exist.
