Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80638, here are decompositions:
- 11 + 80627 = 80638
- 17 + 80621 = 80638
- 71 + 80567 = 80638
- 101 + 80537 = 80638
- 149 + 80489 = 80638
- 167 + 80471 = 80638
- 191 + 80447 = 80638
- 251 + 80387 = 80638
Showing the first eight; more decompositions exist.
