Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42548, here are decompositions:
- 61 + 42487 = 42548
- 97 + 42451 = 42548
- 139 + 42409 = 42548
- 151 + 42397 = 42548
- 157 + 42391 = 42548
- 199 + 42349 = 42548
- 211 + 42337 = 42548
- 241 + 42307 = 42548
Showing the first eight; more decompositions exist.
