Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36820, here are decompositions:
- 11 + 36809 = 36820
- 29 + 36791 = 36820
- 41 + 36779 = 36820
- 53 + 36767 = 36820
- 59 + 36761 = 36820
- 71 + 36749 = 36820
- 107 + 36713 = 36820
- 137 + 36683 = 36820
Showing the first eight; more decompositions exist.
