Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2136, here are decompositions:
- 5 + 2131 = 2136
- 7 + 2129 = 2136
- 23 + 2113 = 2136
- 37 + 2099 = 2136
- 47 + 2089 = 2136
- 53 + 2083 = 2136
- 67 + 2069 = 2136
- 73 + 2063 = 2136
Showing the first eight; more decompositions exist.
