Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1382, here are decompositions:
- 61 + 1321 = 1382
- 79 + 1303 = 1382
- 103 + 1279 = 1382
- 151 + 1231 = 1382
- 181 + 1201 = 1382
- 211 + 1171 = 1382
- 229 + 1153 = 1382
- 313 + 1069 = 1382
Showing the first eight; more decompositions exist.
