Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68378, here are decompositions:
- 7 + 68371 = 68378
- 67 + 68311 = 68378
- 97 + 68281 = 68378
- 139 + 68239 = 68378
- 151 + 68227 = 68378
- 307 + 68071 = 68378
- 337 + 68041 = 68378
- 421 + 67957 = 68378
Showing the first eight; more decompositions exist.
