Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28462, here are decompositions:
- 23 + 28439 = 28462
- 29 + 28433 = 28462
- 53 + 28409 = 28462
- 59 + 28403 = 28462
- 113 + 28349 = 28462
- 173 + 28289 = 28462
- 179 + 28283 = 28462
- 233 + 28229 = 28462
Showing the first eight; more decompositions exist.
