Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5442, here are decompositions:
- 5 + 5437 = 5442
- 11 + 5431 = 5442
- 23 + 5419 = 5442
- 29 + 5413 = 5442
- 43 + 5399 = 5442
- 61 + 5381 = 5442
- 109 + 5333 = 5442
- 139 + 5303 = 5442
Showing the first eight; more decompositions exist.
