Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147880, here are decompositions:
- 17 + 147863 = 147880
- 53 + 147827 = 147880
- 101 + 147779 = 147880
- 107 + 147773 = 147880
- 137 + 147743 = 147880
- 191 + 147689 = 147880
- 233 + 147647 = 147880
- 251 + 147629 = 147880
Showing the first eight; more decompositions exist.
