Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78080, here are decompositions:
- 31 + 78049 = 78080
- 73 + 78007 = 78080
- 97 + 77983 = 78080
- 103 + 77977 = 78080
- 151 + 77929 = 78080
- 181 + 77899 = 78080
- 241 + 77839 = 78080
- 283 + 77797 = 78080
Showing the first eight; more decompositions exist.
