Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13170, here are decompositions:
- 7 + 13163 = 13170
- 11 + 13159 = 13170
- 19 + 13151 = 13170
- 23 + 13147 = 13170
- 43 + 13127 = 13170
- 61 + 13109 = 13170
- 67 + 13103 = 13170
- 71 + 13099 = 13170
Showing the first eight; more decompositions exist.
