Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1206, here are decompositions:
- 5 + 1201 = 1206
- 13 + 1193 = 1206
- 19 + 1187 = 1206
- 43 + 1163 = 1206
- 53 + 1153 = 1206
- 83 + 1123 = 1206
- 89 + 1117 = 1206
- 97 + 1109 = 1206
Showing the first eight; more decompositions exist.
