Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74720, here are decompositions:
- 3 + 74717 = 74720
- 7 + 74713 = 74720
- 13 + 74707 = 74720
- 67 + 74653 = 74720
- 97 + 74623 = 74720
- 109 + 74611 = 74720
- 193 + 74527 = 74720
- 199 + 74521 = 74720
Showing the first eight; more decompositions exist.
