Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103988, here are decompositions:
- 7 + 103981 = 103988
- 19 + 103969 = 103988
- 37 + 103951 = 103988
- 151 + 103837 = 103988
- 307 + 103681 = 103988
- 331 + 103657 = 103988
- 337 + 103651 = 103988
- 397 + 103591 = 103988
Showing the first eight; more decompositions exist.
