Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990244, here are decompositions:

5 + 990239 = 990244
107 + 990137 = 990244
191 + 990053 = 990244
263 + 989981 = 990244
293 + 989951 = 990244
461 + 989783 = 990244
467 + 989777 = 990244
491 + 989753 = 990244

Showing the first eight; more decompositions exist.
