Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80770, here are decompositions:
- 23 + 80747 = 80770
- 83 + 80687 = 80770
- 89 + 80681 = 80770
- 101 + 80669 = 80770
- 113 + 80657 = 80770
- 149 + 80621 = 80770
- 167 + 80603 = 80770
- 233 + 80537 = 80770
Showing the first eight; more decompositions exist.
