Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74816, here are decompositions:
- 19 + 74797 = 74816
- 37 + 74779 = 74816
- 97 + 74719 = 74816
- 103 + 74713 = 74816
- 109 + 74707 = 74816
- 163 + 74653 = 74816
- 193 + 74623 = 74816
- 229 + 74587 = 74816
Showing the first eight; more decompositions exist.
