Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131756, here are decompositions:
- 7 + 131749 = 131756
- 13 + 131743 = 131756
- 43 + 131713 = 131756
- 139 + 131617 = 131756
- 277 + 131479 = 131756
- 307 + 131449 = 131756
- 439 + 131317 = 131756
- 463 + 131293 = 131756
Showing the first eight; more decompositions exist.
