Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673120, here are decompositions:
- 7 + 8673113 = 8673120
- 11 + 8673109 = 8673120
- 13 + 8673107 = 8673120
- 23 + 8673097 = 8673120
- 47 + 8673073 = 8673120
- 83 + 8673037 = 8673120
- 101 + 8673019 = 8673120
- 109 + 8673011 = 8673120
Showing the first eight; more decompositions exist.
