Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990418, here are decompositions:

29 + 990389 = 990418
41 + 990377 = 990418
47 + 990371 = 990418
59 + 990359 = 990418
89 + 990329 = 990418
131 + 990287 = 990418
137 + 990281 = 990418
179 + 990239 = 990418

Showing the first eight; more decompositions exist.
