Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28486, here are decompositions:
- 23 + 28463 = 28486
- 47 + 28439 = 28486
- 53 + 28433 = 28486
- 83 + 28403 = 28486
- 137 + 28349 = 28486
- 167 + 28319 = 28486
- 179 + 28307 = 28486
- 197 + 28289 = 28486
Showing the first eight; more decompositions exist.
