Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137218, here are decompositions:
- 17 + 137201 = 137218
- 41 + 137177 = 137218
- 71 + 137147 = 137218
- 101 + 137117 = 137218
- 131 + 137087 = 137218
- 227 + 136991 = 137218
- 239 + 136979 = 137218
- 269 + 136949 = 137218
Showing the first eight; more decompositions exist.
