Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82406, here are decompositions:
- 13 + 82393 = 82406
- 19 + 82387 = 82406
- 67 + 82339 = 82406
- 127 + 82279 = 82406
- 139 + 82267 = 82406
- 199 + 82207 = 82406
- 223 + 82183 = 82406
- 277 + 82129 = 82406
Showing the first eight; more decompositions exist.
