Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28392, here are decompositions:
- 5 + 28387 = 28392
- 41 + 28351 = 28392
- 43 + 28349 = 28392
- 73 + 28319 = 28392
- 83 + 28309 = 28392
- 103 + 28289 = 28392
- 109 + 28283 = 28392
- 113 + 28279 = 28392
Showing the first eight; more decompositions exist.
