Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90828, here are decompositions:

5 + 90823 = 90828
7 + 90821 = 90828
41 + 90787 = 90828
79 + 90749 = 90828
97 + 90731 = 90828
131 + 90697 = 90828
149 + 90679 = 90828
151 + 90677 = 90828

Showing the first eight; more decompositions exist.
