Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38828, here are decompositions:
- 7 + 38821 = 38828
- 37 + 38791 = 38828
- 61 + 38767 = 38828
- 79 + 38749 = 38828
- 151 + 38677 = 38828
- 157 + 38671 = 38828
- 199 + 38629 = 38828
- 271 + 38557 = 38828
Showing the first eight; more decompositions exist.
