Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71258, here are decompositions:
- 67 + 71191 = 71258
- 97 + 71161 = 71258
- 139 + 71119 = 71258
- 199 + 71059 = 71258
- 277 + 70981 = 71258
- 307 + 70951 = 71258
- 337 + 70921 = 71258
- 367 + 70891 = 71258
Showing the first eight; more decompositions exist.
