Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2192, here are decompositions:
- 13 + 2179 = 2192
- 31 + 2161 = 2192
- 61 + 2131 = 2192
- 79 + 2113 = 2192
- 103 + 2089 = 2192
- 109 + 2083 = 2192
- 139 + 2053 = 2192
- 163 + 2029 = 2192
Showing the first eight; more decompositions exist.
