Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78380, here are decompositions:
- 13 + 78367 = 78380
- 73 + 78307 = 78380
- 79 + 78301 = 78380
- 97 + 78283 = 78380
- 103 + 78277 = 78380
- 139 + 78241 = 78380
- 151 + 78229 = 78380
- 223 + 78157 = 78380
Showing the first eight; more decompositions exist.
