Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80090, here are decompositions:

13 + 80077 = 80090
19 + 80071 = 80090
103 + 79987 = 80090
151 + 79939 = 80090
223 + 79867 = 80090
229 + 79861 = 80090
277 + 79813 = 80090
313 + 79777 = 80090

Showing the first eight; more decompositions exist.
