Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90066, here are decompositions:

7 + 90059 = 90066
13 + 90053 = 90066
43 + 90023 = 90066
47 + 90019 = 90066
59 + 90007 = 90066
83 + 89983 = 90066
89 + 89977 = 90066
103 + 89963 = 90066

Showing the first eight; more decompositions exist.
