Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137320, here are decompositions:
- 17 + 137303 = 137320
- 41 + 137279 = 137320
- 47 + 137273 = 137320
- 101 + 137219 = 137320
- 137 + 137183 = 137320
- 167 + 137153 = 137320
- 173 + 137147 = 137320
- 233 + 137087 = 137320
Showing the first eight; more decompositions exist.
