Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27168, here are decompositions:
- 41 + 27127 = 27168
- 59 + 27109 = 27168
- 61 + 27107 = 27168
- 101 + 27067 = 27168
- 107 + 27061 = 27168
- 109 + 27059 = 27168
- 137 + 27031 = 27168
- 151 + 27017 = 27168
Showing the first eight; more decompositions exist.
