Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74724, here are decompositions:
- 5 + 74719 = 74724
- 7 + 74717 = 74724
- 11 + 74713 = 74724
- 17 + 74707 = 74724
- 37 + 74687 = 74724
- 71 + 74653 = 74724
- 101 + 74623 = 74724
- 113 + 74611 = 74724
Showing the first eight; more decompositions exist.
