Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990460, here are decompositions:

71 + 990389 = 990460
83 + 990377 = 990460
89 + 990371 = 990460
101 + 990359 = 990460
131 + 990329 = 990460
137 + 990323 = 990460
167 + 990293 = 990460
173 + 990287 = 990460

Showing the first eight; more decompositions exist.
