Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990944, here are decompositions:

103 + 990841 = 990944
211 + 990733 = 990944
271 + 990673 = 990944
307 + 990637 = 990944
313 + 990631 = 990944
397 + 990547 = 990944
421 + 990523 = 990944
433 + 990511 = 990944

Showing the first eight; more decompositions exist.
