Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27142, here are decompositions:
- 83 + 27059 = 27142
- 131 + 27011 = 27142
- 149 + 26993 = 27142
- 191 + 26951 = 27142
- 239 + 26903 = 27142
- 251 + 26891 = 27142
- 263 + 26879 = 27142
- 281 + 26861 = 27142
Showing the first eight; more decompositions exist.
