Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81262, here are decompositions:
- 23 + 81239 = 81262
- 29 + 81233 = 81262
- 59 + 81203 = 81262
- 89 + 81173 = 81262
- 131 + 81131 = 81262
- 179 + 81083 = 81262
- 191 + 81071 = 81262
- 239 + 81023 = 81262
Showing the first eight; more decompositions exist.
