Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90080, here are decompositions:

7 + 90073 = 90080
13 + 90067 = 90080
61 + 90019 = 90080
73 + 90007 = 90080
79 + 90001 = 90080
97 + 89983 = 90080
103 + 89977 = 90080
157 + 89923 = 90080

Showing the first eight; more decompositions exist.
