Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80400, here are decompositions:
- 13 + 80387 = 80400
- 31 + 80369 = 80400
- 37 + 80363 = 80400
- 53 + 80347 = 80400
- 59 + 80341 = 80400
- 71 + 80329 = 80400
- 83 + 80317 = 80400
- 113 + 80287 = 80400
Showing the first eight; more decompositions exist.
