Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133740, here are decompositions:
- 7 + 133733 = 133740
- 17 + 133723 = 133740
- 23 + 133717 = 133740
- 29 + 133711 = 133740
- 31 + 133709 = 133740
- 43 + 133697 = 133740
- 67 + 133673 = 133740
- 71 + 133669 = 133740
Showing the first eight; more decompositions exist.
