Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147730, here are decompositions:
- 3 + 147727 = 147730
- 41 + 147689 = 147730
- 59 + 147671 = 147730
- 83 + 147647 = 147730
- 101 + 147629 = 147730
- 113 + 147617 = 147730
- 173 + 147557 = 147730
- 179 + 147551 = 147730
Showing the first eight; more decompositions exist.
