Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80486, here are decompositions:
- 13 + 80473 = 80486
- 37 + 80449 = 80486
- 79 + 80407 = 80486
- 139 + 80347 = 80486
- 157 + 80329 = 80486
- 199 + 80287 = 80486
- 223 + 80263 = 80486
- 277 + 80209 = 80486
Showing the first eight; more decompositions exist.
