Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81276, here are decompositions:
- 37 + 81239 = 81276
- 43 + 81233 = 81276
- 53 + 81223 = 81276
- 73 + 81203 = 81276
- 79 + 81197 = 81276
- 103 + 81173 = 81276
- 113 + 81163 = 81276
- 157 + 81119 = 81276
Showing the first eight; more decompositions exist.
