Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5478, here are decompositions:
- 7 + 5471 = 5478
- 29 + 5449 = 5478
- 37 + 5441 = 5478
- 41 + 5437 = 5478
- 47 + 5431 = 5478
- 59 + 5419 = 5478
- 61 + 5417 = 5478
- 71 + 5407 = 5478
Showing the first eight; more decompositions exist.
