Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28584, here are decompositions:
- 5 + 28579 = 28584
- 11 + 28573 = 28584
- 13 + 28571 = 28584
- 37 + 28547 = 28584
- 43 + 28541 = 28584
- 47 + 28537 = 28584
- 67 + 28517 = 28584
- 71 + 28513 = 28584
Showing the first eight; more decompositions exist.
