Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27120, here are decompositions:
- 11 + 27109 = 27120
- 13 + 27107 = 27120
- 17 + 27103 = 27120
- 29 + 27091 = 27120
- 43 + 27077 = 27120
- 47 + 27073 = 27120
- 53 + 27067 = 27120
- 59 + 27061 = 27120
Showing the first eight; more decompositions exist.
