Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90918, here are decompositions:

7 + 90911 = 90918
11 + 90907 = 90918
17 + 90901 = 90918
31 + 90887 = 90918
71 + 90847 = 90918
97 + 90821 = 90918
131 + 90787 = 90918
239 + 90679 = 90918

Showing the first eight; more decompositions exist.
