Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38872, here are decompositions:
- 5 + 38867 = 38872
- 11 + 38861 = 38872
- 89 + 38783 = 38872
- 149 + 38723 = 38872
- 173 + 38699 = 38872
- 179 + 38693 = 38872
- 233 + 38639 = 38872
- 263 + 38609 = 38872
Showing the first eight; more decompositions exist.
