Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990634, here are decompositions:

3 + 990631 = 990634
41 + 990593 = 990634
131 + 990503 = 990634
137 + 990497 = 990634
251 + 990383 = 990634
257 + 990377 = 990634
263 + 990371 = 990634
311 + 990323 = 990634

Showing the first eight; more decompositions exist.
