Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43554, here are decompositions:
- 11 + 43543 = 43554
- 13 + 43541 = 43554
- 37 + 43517 = 43554
- 67 + 43487 = 43554
- 73 + 43481 = 43554
- 97 + 43457 = 43554
- 103 + 43451 = 43554
- 113 + 43441 = 43554
Showing the first eight; more decompositions exist.
