Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55540, here are decompositions:
- 11 + 55529 = 55540
- 29 + 55511 = 55540
- 53 + 55487 = 55540
- 71 + 55469 = 55540
- 83 + 55457 = 55540
- 101 + 55439 = 55540
- 167 + 55373 = 55540
- 197 + 55343 = 55540
Showing the first eight; more decompositions exist.
