Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1292, here are decompositions:
- 3 + 1289 = 1292
- 13 + 1279 = 1292
- 43 + 1249 = 1292
- 61 + 1231 = 1292
- 79 + 1213 = 1292
- 139 + 1153 = 1292
- 163 + 1129 = 1292
- 199 + 1093 = 1292
Showing the first eight; more decompositions exist.
