Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108, here are decompositions:
- 5 + 103 = 108
- 7 + 101 = 108
- 11 + 97 = 108
- 19 + 89 = 108
- 29 + 79 = 108
- 37 + 71 = 108
- 41 + 67 = 108
- 47 + 61 = 108
Showing the first eight; more decompositions exist.
