Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2116, here are decompositions:
- 3 + 2113 = 2116
- 5 + 2111 = 2116
- 17 + 2099 = 2116
- 29 + 2087 = 2116
- 47 + 2069 = 2116
- 53 + 2063 = 2116
- 89 + 2027 = 2116
- 113 + 2003 = 2116
Showing the first eight; more decompositions exist.
