Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1192, here are decompositions:
- 5 + 1187 = 1192
- 11 + 1181 = 1192
- 29 + 1163 = 1192
- 41 + 1151 = 1192
- 83 + 1109 = 1192
- 89 + 1103 = 1192
- 101 + 1091 = 1192
- 131 + 1061 = 1192
Showing the first eight; more decompositions exist.
