Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80644, here are decompositions:
- 17 + 80627 = 80644
- 23 + 80621 = 80644
- 41 + 80603 = 80644
- 107 + 80537 = 80644
- 131 + 80513 = 80644
- 173 + 80471 = 80644
- 197 + 80447 = 80644
- 257 + 80387 = 80644
Showing the first eight; more decompositions exist.
