Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80388, here are decompositions:
- 19 + 80369 = 80388
- 41 + 80347 = 80388
- 47 + 80341 = 80388
- 59 + 80329 = 80388
- 71 + 80317 = 80388
- 79 + 80309 = 80388
- 101 + 80287 = 80388
- 109 + 80279 = 80388
Showing the first eight; more decompositions exist.
