Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90920, here are decompositions:

3 + 90917 = 90920
13 + 90907 = 90920
19 + 90901 = 90920
73 + 90847 = 90920
79 + 90841 = 90920
97 + 90823 = 90920
127 + 90793 = 90920
211 + 90709 = 90920

Showing the first eight; more decompositions exist.
