Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133688, here are decompositions:
- 19 + 133669 = 133688
- 31 + 133657 = 133688
- 241 + 133447 = 133688
- 271 + 133417 = 133688
- 337 + 133351 = 133688
- 367 + 133321 = 133688
- 409 + 133279 = 133688
- 487 + 133201 = 133688
Showing the first eight; more decompositions exist.
