Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27144, here are decompositions:
- 17 + 27127 = 27144
- 37 + 27107 = 27144
- 41 + 27103 = 27144
- 53 + 27091 = 27144
- 67 + 27077 = 27144
- 71 + 27073 = 27144
- 83 + 27061 = 27144
- 101 + 27043 = 27144
Showing the first eight; more decompositions exist.
