Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133308, here are decompositions:
- 5 + 133303 = 133308
- 29 + 133279 = 133308
- 31 + 133277 = 133308
- 37 + 133271 = 133308
- 47 + 133261 = 133308
- 67 + 133241 = 133308
- 107 + 133201 = 133308
- 139 + 133169 = 133308
Showing the first eight; more decompositions exist.
