Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45458, here are decompositions:
- 19 + 45439 = 45458
- 31 + 45427 = 45458
- 97 + 45361 = 45458
- 139 + 45319 = 45458
- 151 + 45307 = 45458
- 199 + 45259 = 45458
- 211 + 45247 = 45458
- 277 + 45181 = 45458
Showing the first eight; more decompositions exist.
