Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990496, here are decompositions:

107 + 990389 = 990496
113 + 990383 = 990496
137 + 990359 = 990496
167 + 990329 = 990496
173 + 990323 = 990496
257 + 990239 = 990496
317 + 990179 = 990496
359 + 990137 = 990496

Showing the first eight; more decompositions exist.
