Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39542, here are decompositions:
- 31 + 39511 = 39542
- 43 + 39499 = 39542
- 103 + 39439 = 39542
- 199 + 39343 = 39542
- 229 + 39313 = 39542
- 241 + 39301 = 39542
- 313 + 39229 = 39542
- 379 + 39163 = 39542
Showing the first eight; more decompositions exist.
