Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133392, here are decompositions:
- 5 + 133387 = 133392
- 13 + 133379 = 133392
- 41 + 133351 = 133392
- 43 + 133349 = 133392
- 71 + 133321 = 133392
- 73 + 133319 = 133392
- 89 + 133303 = 133392
- 109 + 133283 = 133392
Showing the first eight; more decompositions exist.
