Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74748, here are decompositions:
- 17 + 74731 = 74748
- 19 + 74729 = 74748
- 29 + 74719 = 74748
- 31 + 74717 = 74748
- 41 + 74707 = 74748
- 61 + 74687 = 74748
- 137 + 74611 = 74748
- 139 + 74609 = 74748
Showing the first eight; more decompositions exist.
