Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38398, here are decompositions:
- 5 + 38393 = 38398
- 47 + 38351 = 38398
- 71 + 38327 = 38398
- 137 + 38261 = 38398
- 167 + 38231 = 38398
- 179 + 38219 = 38398
- 197 + 38201 = 38398
- 359 + 38039 = 38398
Showing the first eight; more decompositions exist.
