Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28582, here are decompositions:
- 3 + 28579 = 28582
- 11 + 28571 = 28582
- 23 + 28559 = 28582
- 41 + 28541 = 28582
- 83 + 28499 = 28582
- 89 + 28493 = 28582
- 149 + 28433 = 28582
- 173 + 28409 = 28582
Showing the first eight; more decompositions exist.
