Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28562, here are decompositions:
- 3 + 28559 = 28562
- 13 + 28549 = 28562
- 151 + 28411 = 28562
- 211 + 28351 = 28562
- 283 + 28279 = 28562
- 379 + 28183 = 28562
- 439 + 28123 = 28562
- 463 + 28099 = 28562
Showing the first eight; more decompositions exist.
