Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133428, here are decompositions:
- 11 + 133417 = 133428
- 37 + 133391 = 133428
- 41 + 133387 = 133428
- 79 + 133349 = 133428
- 101 + 133327 = 133428
- 107 + 133321 = 133428
- 109 + 133319 = 133428
- 149 + 133279 = 133428
Showing the first eight; more decompositions exist.
