Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131888, here are decompositions:
- 109 + 131779 = 131888
- 139 + 131749 = 131888
- 157 + 131731 = 131888
- 181 + 131707 = 131888
- 271 + 131617 = 131888
- 277 + 131611 = 131888
- 307 + 131581 = 131888
- 409 + 131479 = 131888
Showing the first eight; more decompositions exist.
