Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80378, here are decompositions:
- 31 + 80347 = 80378
- 37 + 80341 = 80378
- 61 + 80317 = 80378
- 127 + 80251 = 80378
- 139 + 80239 = 80378
- 157 + 80221 = 80378
- 211 + 80167 = 80378
- 229 + 80149 = 80378
Showing the first eight; more decompositions exist.
