Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43542, here are decompositions:
- 43 + 43499 = 43542
- 61 + 43481 = 43542
- 101 + 43441 = 43542
- 131 + 43411 = 43542
- 139 + 43403 = 43542
- 151 + 43391 = 43542
- 211 + 43331 = 43542
- 223 + 43319 = 43542
Showing the first eight; more decompositions exist.
