Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1234, here are decompositions:
- 3 + 1231 = 1234
- 5 + 1229 = 1234
- 11 + 1223 = 1234
- 17 + 1217 = 1234
- 41 + 1193 = 1234
- 47 + 1187 = 1234
- 53 + 1181 = 1234
- 71 + 1163 = 1234
Showing the first eight; more decompositions exist.
