Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90838, here are decompositions:

5 + 90833 = 90838
17 + 90821 = 90838
89 + 90749 = 90838
107 + 90731 = 90838
179 + 90659 = 90838
191 + 90647 = 90838
197 + 90641 = 90838
239 + 90599 = 90838

Showing the first eight; more decompositions exist.
