Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55584, here are decompositions:
- 5 + 55579 = 55584
- 37 + 55547 = 55584
- 43 + 55541 = 55584
- 73 + 55511 = 55584
- 83 + 55501 = 55584
- 97 + 55487 = 55584
- 127 + 55457 = 55584
- 173 + 55411 = 55584
Showing the first eight; more decompositions exist.
