Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80818, here are decompositions:
- 29 + 80789 = 80818
- 41 + 80777 = 80818
- 71 + 80747 = 80818
- 131 + 80687 = 80818
- 137 + 80681 = 80818
- 149 + 80669 = 80818
- 167 + 80651 = 80818
- 191 + 80627 = 80818
Showing the first eight; more decompositions exist.
