Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80564, here are decompositions:
- 7 + 80557 = 80564
- 37 + 80527 = 80564
- 73 + 80491 = 80564
- 157 + 80407 = 80564
- 223 + 80341 = 80564
- 277 + 80287 = 80564
- 313 + 80251 = 80564
- 331 + 80233 = 80564
Showing the first eight; more decompositions exist.
