Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990604, here are decompositions:

5 + 990599 = 990604
11 + 990593 = 990604
101 + 990503 = 990604
107 + 990497 = 990604
227 + 990377 = 990604
233 + 990371 = 990604
281 + 990323 = 990604
311 + 990293 = 990604

Showing the first eight; more decompositions exist.
