Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39388, here are decompositions:
- 5 + 39383 = 39388
- 17 + 39371 = 39388
- 29 + 39359 = 39388
- 47 + 39341 = 39388
- 71 + 39317 = 39388
- 137 + 39251 = 39388
- 149 + 39239 = 39388
- 179 + 39209 = 39388
Showing the first eight; more decompositions exist.
