Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147748, here are decompositions:
- 5 + 147743 = 147748
- 59 + 147689 = 147748
- 101 + 147647 = 147748
- 131 + 147617 = 147748
- 191 + 147557 = 147748
- 197 + 147551 = 147748
- 347 + 147401 = 147748
- 401 + 147347 = 147748
Showing the first eight; more decompositions exist.
