Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30080, here are decompositions:

67 + 30013 = 30080
97 + 29983 = 30080
163 + 29917 = 30080
199 + 29881 = 30080
229 + 29851 = 30080
277 + 29803 = 30080
397 + 29683 = 30080
409 + 29671 = 30080

Showing the first eight; more decompositions exist.
