Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39478, here are decompositions:
- 17 + 39461 = 39478
- 59 + 39419 = 39478
- 107 + 39371 = 39478
- 137 + 39341 = 39478
- 227 + 39251 = 39478
- 239 + 39239 = 39478
- 251 + 39227 = 39478
- 269 + 39209 = 39478
Showing the first eight; more decompositions exist.
