Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28332, here are decompositions:
- 13 + 28319 = 28332
- 23 + 28309 = 28332
- 43 + 28289 = 28332
- 53 + 28279 = 28332
- 103 + 28229 = 28332
- 113 + 28219 = 28332
- 131 + 28201 = 28332
- 149 + 28183 = 28332
Showing the first eight; more decompositions exist.
