Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188766, here are decompositions:
- 13 + 188753 = 188766
- 37 + 188729 = 188766
- 47 + 188719 = 188766
- 59 + 188707 = 188766
- 73 + 188693 = 188766
- 79 + 188687 = 188766
- 89 + 188677 = 188766
- 113 + 188653 = 188766
Showing the first eight; more decompositions exist.
