Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506442, here are decompositions:
- 29 + 33506413 = 33506442
- 41 + 33506401 = 33506442
- 43 + 33506399 = 33506442
- 83 + 33506359 = 33506442
- 131 + 33506311 = 33506442
- 181 + 33506261 = 33506442
- 191 + 33506251 = 33506442
- 223 + 33506219 = 33506442
Showing the first eight; more decompositions exist.
