Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131704, here are decompositions:
- 3 + 131701 = 131704
- 17 + 131687 = 131704
- 113 + 131591 = 131704
- 197 + 131507 = 131704
- 227 + 131477 = 131704
- 257 + 131447 = 131704
- 263 + 131441 = 131704
- 347 + 131357 = 131704
Showing the first eight; more decompositions exist.
