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.
