Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27138, here are decompositions:
- 11 + 27127 = 27138
- 29 + 27109 = 27138
- 31 + 27107 = 27138
- 47 + 27091 = 27138
- 61 + 27077 = 27138
- 71 + 27067 = 27138
- 79 + 27059 = 27138
- 107 + 27031 = 27138
Showing the first eight; more decompositions exist.
