Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75442, here are decompositions:
- 5 + 75437 = 75442
- 11 + 75431 = 75442
- 41 + 75401 = 75442
- 53 + 75389 = 75442
- 89 + 75353 = 75442
- 113 + 75329 = 75442
- 173 + 75269 = 75442
- 233 + 75209 = 75442
Showing the first eight; more decompositions exist.
