Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27066, here are decompositions:
- 5 + 27061 = 27066
- 7 + 27059 = 27066
- 23 + 27043 = 27066
- 73 + 26993 = 27066
- 79 + 26987 = 27066
- 107 + 26959 = 27066
- 113 + 26953 = 27066
- 139 + 26927 = 27066
Showing the first eight; more decompositions exist.
