Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82490, here are decompositions:
- 3 + 82487 = 82490
- 7 + 82483 = 82490
- 19 + 82471 = 82490
- 97 + 82393 = 82490
- 103 + 82387 = 82490
- 139 + 82351 = 82490
- 151 + 82339 = 82490
- 211 + 82279 = 82490
Showing the first eight; more decompositions exist.
