Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493428, here are decompositions:
- 37 + 33493391 = 33493428
- 41 + 33493387 = 33493428
- 107 + 33493321 = 33493428
- 149 + 33493279 = 33493428
- 211 + 33493217 = 33493428
- 257 + 33493171 = 33493428
- 271 + 33493157 = 33493428
- 307 + 33493121 = 33493428
Showing the first eight; more decompositions exist.
