Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27158, here are decompositions:
- 31 + 27127 = 27158
- 67 + 27091 = 27158
- 97 + 27061 = 27158
- 127 + 27031 = 27158
- 199 + 26959 = 27158
- 211 + 26947 = 27158
- 277 + 26881 = 27158
- 337 + 26821 = 27158
Showing the first eight; more decompositions exist.
