Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990616, here are decompositions:

17 + 990599 = 990616
23 + 990593 = 990616
113 + 990503 = 990616
227 + 990389 = 990616
233 + 990383 = 990616
239 + 990377 = 990616
257 + 990359 = 990616
293 + 990323 = 990616

Showing the first eight; more decompositions exist.
