Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42752, here are decompositions:
- 43 + 42709 = 42752
- 103 + 42649 = 42752
- 109 + 42643 = 42752
- 163 + 42589 = 42752
- 181 + 42571 = 42752
- 349 + 42403 = 42752
- 373 + 42379 = 42752
- 379 + 42373 = 42752
Showing the first eight; more decompositions exist.
