Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147940, here are decompositions:
- 3 + 147937 = 147940
- 59 + 147881 = 147940
- 113 + 147827 = 147940
- 167 + 147773 = 147940
- 179 + 147761 = 147940
- 197 + 147743 = 147940
- 251 + 147689 = 147940
- 269 + 147671 = 147940
Showing the first eight; more decompositions exist.
