Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990146, here are decompositions:

103 + 990043 = 990146
109 + 990037 = 990146
229 + 989917 = 990146
277 + 989869 = 990146
307 + 989839 = 990146
349 + 989797 = 990146
397 + 989749 = 990146
499 + 989647 = 990146

Showing the first eight; more decompositions exist.
