Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28350, here are decompositions:
- 31 + 28319 = 28350
- 41 + 28309 = 28350
- 43 + 28307 = 28350
- 53 + 28297 = 28350
- 61 + 28289 = 28350
- 67 + 28283 = 28350
- 71 + 28279 = 28350
- 73 + 28277 = 28350
Showing the first eight; more decompositions exist.
