Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1322, here are decompositions:
- 3 + 1319 = 1322
- 19 + 1303 = 1322
- 31 + 1291 = 1322
- 43 + 1279 = 1322
- 73 + 1249 = 1322
- 109 + 1213 = 1322
- 151 + 1171 = 1322
- 193 + 1129 = 1322
Showing the first eight; more decompositions exist.
