Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990226, here are decompositions:

47 + 990179 = 990226
89 + 990137 = 990226
173 + 990053 = 990226
227 + 989999 = 990226
317 + 989909 = 990226
353 + 989873 = 990226
389 + 989837 = 990226
443 + 989783 = 990226

Showing the first eight; more decompositions exist.
