Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38542, here are decompositions:
- 41 + 38501 = 38542
- 83 + 38459 = 38542
- 89 + 38453 = 38542
- 149 + 38393 = 38542
- 191 + 38351 = 38542
- 239 + 38303 = 38542
- 269 + 38273 = 38542
- 281 + 38261 = 38542
Showing the first eight; more decompositions exist.
