Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148378, here are decompositions:
- 11 + 148367 = 148378
- 17 + 148361 = 148378
- 47 + 148331 = 148378
- 149 + 148229 = 148378
- 179 + 148199 = 148378
- 227 + 148151 = 148378
- 239 + 148139 = 148378
- 317 + 148061 = 148378
Showing the first eight; more decompositions exist.
