Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39442, here are decompositions:
- 3 + 39439 = 39442
- 23 + 39419 = 39442
- 59 + 39383 = 39442
- 71 + 39371 = 39442
- 83 + 39359 = 39442
- 101 + 39341 = 39442
- 149 + 39293 = 39442
- 191 + 39251 = 39442
Showing the first eight; more decompositions exist.
