Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27218, here are decompositions:
- 7 + 27211 = 27218
- 109 + 27109 = 27218
- 127 + 27091 = 27218
- 151 + 27067 = 27218
- 157 + 27061 = 27218
- 271 + 26947 = 27218
- 337 + 26881 = 27218
- 379 + 26839 = 27218
Showing the first eight; more decompositions exist.
