Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133288, here are decompositions:
- 5 + 133283 = 133288
- 11 + 133277 = 133288
- 17 + 133271 = 133288
- 47 + 133241 = 133288
- 101 + 133187 = 133288
- 131 + 133157 = 133288
- 167 + 133121 = 133288
- 179 + 133109 = 133288
Showing the first eight; more decompositions exist.
