Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990550, here are decompositions:

3 + 990547 = 990550
47 + 990503 = 990550
53 + 990497 = 990550
167 + 990383 = 990550
173 + 990377 = 990550
179 + 990371 = 990550
191 + 990359 = 990550
227 + 990323 = 990550

Showing the first eight; more decompositions exist.
