Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17542, here are decompositions:
- 3 + 17539 = 17542
- 23 + 17519 = 17542
- 53 + 17489 = 17542
- 59 + 17483 = 17542
- 71 + 17471 = 17542
- 149 + 17393 = 17542
- 191 + 17351 = 17542
- 251 + 17291 = 17542
Showing the first eight; more decompositions exist.
