Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27210, here are decompositions:
- 13 + 27197 = 27210
- 19 + 27191 = 27210
- 31 + 27179 = 27210
- 67 + 27143 = 27210
- 83 + 27127 = 27210
- 101 + 27109 = 27210
- 103 + 27107 = 27210
- 107 + 27103 = 27210
Showing the first eight; more decompositions exist.
