Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990758, here are decompositions:

127 + 990631 = 990758
199 + 990559 = 990758
211 + 990547 = 990758
229 + 990529 = 990758
271 + 990487 = 990758
397 + 990361 = 990758
409 + 990349 = 990758
499 + 990259 = 990758

Showing the first eight; more decompositions exist.
