Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5538, here are decompositions:
- 7 + 5531 = 5538
- 11 + 5527 = 5538
- 17 + 5521 = 5538
- 19 + 5519 = 5538
- 31 + 5507 = 5538
- 37 + 5501 = 5538
- 59 + 5479 = 5538
- 61 + 5477 = 5538
Showing the first eight; more decompositions exist.
