Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990836, here are decompositions:

37 + 990799 = 990836
103 + 990733 = 990836
163 + 990673 = 990836
193 + 990643 = 990836
199 + 990637 = 990836
277 + 990559 = 990836
307 + 990529 = 990836
313 + 990523 = 990836

Showing the first eight; more decompositions exist.
