Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42508, here are decompositions:
- 17 + 42491 = 42508
- 41 + 42467 = 42508
- 47 + 42461 = 42508
- 71 + 42437 = 42508
- 101 + 42407 = 42508
- 149 + 42359 = 42508
- 227 + 42281 = 42508
- 251 + 42257 = 42508
Showing the first eight; more decompositions exist.
