Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78160, here are decompositions:
- 3 + 78157 = 78160
- 23 + 78137 = 78160
- 59 + 78101 = 78160
- 101 + 78059 = 78160
- 191 + 77969 = 78160
- 227 + 77933 = 78160
- 293 + 77867 = 78160
- 311 + 77849 = 78160
Showing the first eight; more decompositions exist.
