Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43442, here are decompositions:
- 31 + 43411 = 43442
- 43 + 43399 = 43442
- 151 + 43291 = 43442
- 181 + 43261 = 43442
- 241 + 43201 = 43442
- 283 + 43159 = 43442
- 349 + 43093 = 43442
- 379 + 43063 = 43442
Showing the first eight; more decompositions exist.
