Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 584, here are decompositions:
- 7 + 577 = 584
- 13 + 571 = 584
- 37 + 547 = 584
- 43 + 541 = 584
- 61 + 523 = 584
- 97 + 487 = 584
- 127 + 457 = 584
- 151 + 433 = 584
Showing the first eight; more decompositions exist.
