Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103668, here are decompositions:
- 11 + 103657 = 103668
- 17 + 103651 = 103668
- 101 + 103567 = 103668
- 107 + 103561 = 103668
- 139 + 103529 = 103668
- 157 + 103511 = 103668
- 197 + 103471 = 103668
- 211 + 103457 = 103668
Showing the first eight; more decompositions exist.
