Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74880, here are decompositions:
- 7 + 74873 = 74880
- 11 + 74869 = 74880
- 19 + 74861 = 74880
- 23 + 74857 = 74880
- 37 + 74843 = 74880
- 53 + 74827 = 74880
- 59 + 74821 = 74880
- 83 + 74797 = 74880
Showing the first eight; more decompositions exist.
