Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27240, here are decompositions:
- 29 + 27211 = 27240
- 43 + 27197 = 27240
- 61 + 27179 = 27240
- 97 + 27143 = 27240
- 113 + 27127 = 27240
- 131 + 27109 = 27240
- 137 + 27103 = 27240
- 149 + 27091 = 27240
Showing the first eight; more decompositions exist.
