Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80722, here are decompositions:
- 41 + 80681 = 80722
- 53 + 80669 = 80722
- 71 + 80651 = 80722
- 101 + 80621 = 80722
- 233 + 80489 = 80722
- 251 + 80471 = 80722
- 293 + 80429 = 80722
- 353 + 80369 = 80722
Showing the first eight; more decompositions exist.
