Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75400, here are decompositions:
- 11 + 75389 = 75400
- 23 + 75377 = 75400
- 47 + 75353 = 75400
- 53 + 75347 = 75400
- 71 + 75329 = 75400
- 131 + 75269 = 75400
- 173 + 75227 = 75400
- 191 + 75209 = 75400
Showing the first eight; more decompositions exist.
