Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147666, here are decompositions:
- 5 + 147661 = 147666
- 19 + 147647 = 147666
- 37 + 147629 = 147666
- 53 + 147613 = 147666
- 59 + 147607 = 147666
- 83 + 147583 = 147666
- 109 + 147557 = 147666
- 149 + 147517 = 147666
Showing the first eight; more decompositions exist.
