Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33428, here are decompositions:
- 19 + 33409 = 33428
- 37 + 33391 = 33428
- 79 + 33349 = 33428
- 97 + 33331 = 33428
- 127 + 33301 = 33428
- 139 + 33289 = 33428
- 181 + 33247 = 33428
- 229 + 33199 = 33428
Showing the first eight; more decompositions exist.
