Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38948, here are decompositions:
- 31 + 38917 = 38948
- 97 + 38851 = 38948
- 109 + 38839 = 38948
- 127 + 38821 = 38948
- 157 + 38791 = 38948
- 181 + 38767 = 38948
- 199 + 38749 = 38948
- 211 + 38737 = 38948
Showing the first eight; more decompositions exist.
