Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137170, here are decompositions:
- 17 + 137153 = 137170
- 23 + 137147 = 137170
- 53 + 137117 = 137170
- 83 + 137087 = 137170
- 179 + 136991 = 137170
- 191 + 136979 = 137170
- 197 + 136973 = 137170
- 227 + 136943 = 137170
Showing the first eight; more decompositions exist.
