Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43478, here are decompositions:
- 37 + 43441 = 43478
- 67 + 43411 = 43478
- 79 + 43399 = 43478
- 157 + 43321 = 43478
- 241 + 43237 = 43478
- 271 + 43207 = 43478
- 277 + 43201 = 43478
- 499 + 42979 = 43478
Showing the first eight; more decompositions exist.
