Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133284, here are decompositions:
- 5 + 133279 = 133284
- 7 + 133277 = 133284
- 13 + 133271 = 133284
- 23 + 133261 = 133284
- 31 + 133253 = 133284
- 43 + 133241 = 133284
- 71 + 133213 = 133284
- 83 + 133201 = 133284
Showing the first eight; more decompositions exist.
