Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557442, here are decompositions:
- 13 + 33557429 = 33557442
- 19 + 33557423 = 33557442
- 29 + 33557413 = 33557442
- 31 + 33557411 = 33557442
- 43 + 33557399 = 33557442
- 101 + 33557341 = 33557442
- 103 + 33557339 = 33557442
- 239 + 33557203 = 33557442
Showing the first eight; more decompositions exist.
