Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131936, here are decompositions:
- 3 + 131933 = 131936
- 37 + 131899 = 131936
- 43 + 131893 = 131936
- 97 + 131839 = 131936
- 139 + 131797 = 131936
- 157 + 131779 = 131936
- 193 + 131743 = 131936
- 223 + 131713 = 131936
Showing the first eight; more decompositions exist.
