Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40378, here are decompositions:
- 17 + 40361 = 40378
- 89 + 40289 = 40378
- 101 + 40277 = 40378
- 137 + 40241 = 40378
- 227 + 40151 = 40378
- 251 + 40127 = 40378
- 347 + 40031 = 40378
- 389 + 39989 = 40378
Showing the first eight; more decompositions exist.
