Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12378, here are decompositions:
- 5 + 12373 = 12378
- 31 + 12347 = 12378
- 89 + 12289 = 12378
- 97 + 12281 = 12378
- 101 + 12277 = 12378
- 109 + 12269 = 12378
- 127 + 12251 = 12378
- 137 + 12241 = 12378
Showing the first eight; more decompositions exist.
