Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1342, here are decompositions:
- 23 + 1319 = 1342
- 41 + 1301 = 1342
- 53 + 1289 = 1342
- 59 + 1283 = 1342
- 83 + 1259 = 1342
- 113 + 1229 = 1342
- 149 + 1193 = 1342
- 179 + 1163 = 1342
Showing the first eight; more decompositions exist.
