Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103788, here are decompositions:
- 19 + 103769 = 103788
- 89 + 103699 = 103788
- 101 + 103687 = 103788
- 107 + 103681 = 103788
- 131 + 103657 = 103788
- 137 + 103651 = 103788
- 197 + 103591 = 103788
- 211 + 103577 = 103788
Showing the first eight; more decompositions exist.
