Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38918, here are decompositions:
- 67 + 38851 = 38918
- 79 + 38839 = 38918
- 97 + 38821 = 38918
- 127 + 38791 = 38918
- 151 + 38767 = 38918
- 181 + 38737 = 38918
- 211 + 38707 = 38918
- 241 + 38677 = 38918
Showing the first eight; more decompositions exist.
